Every vehicle's engine wears out as a result of friction during normal operation. This friction causes wear of the cylinder walls, which leads to compression loss. Lost compression results in your engine having less power - it runs poorly and has sluggish acceleration. It also can cause increased oil burning, exhaust smoking, and poor fuel economy. RESTORE Engine Restorer and Lubricant is a unique engine additive that repairs those worn-out areas in the cylinder wall thereby restoring cylinder compression and improving engine performance to nearly new original condition.
RESTORE Engine Restorer is the only product that contains the proprietary CSL (copper, silver, lead micro- spheres) formula. This technologically advanced formulation has unique properties that actually fill in and seal micro- leaks in the cylinder wall. The result is increased engine compression and more engine power.
By using 10% RESTORE Engine Restorer as an initial (curative) treatment & 5% RESTORE on a regular basis at every oil change, you will keep the compression ratio of all cylinders at near original levels. You will feel the difference when you drive, your vehicle will have more power, sharper acceleration and it will run more smoothly because the compression is balanced across all cylinders. In addition, if your engine has blow-by, is burning oil, producing blue smoke or is excessively noisy because of engine wear, RESTORE will reduce and improve this situation.
Yes, RESTORE Engine Restorer is an extreme pressure lubricant in its own right, but it also compensates for engine wear.
Yes, RESTORE Engine Restorer may be used with any type of mineral, semi-synthetic or synthetic motor oil such as those available on any supermarket shelf. For best results though, we recommend against using RESTORE with oils containing plant esters, e.g. Castrol Magnatec, Silkolene R, Motul, Redline or oils describing themselves as Racing or Motorsports oils. Ester oils contain positively charged molecules that stick to metal surfaces to enhance lubrication, but they can work against RESTORE, slowing the repair process down considerably. RESTORE is best used in a standard motor oil of the specification and grade recommended for your engine. Once RESTORE has worked its 'magic' you can go back to your preferred friction-reducing package at the next oil change interval if you wish.
No, RESTORE Engine Restorer does not change the viscosity or the characteristics of the motor oil to which it is added. It is not a viscosity improver or an oil additive, but an engine additive. It adds metal back into the scratches cut into the friction-producing surface metal by normal engine wear.
High Mileage motor oils are simply high viscosity oils, with a higher SAE rating e.g. 20W50. They are intended to compensate for wear in high mileage engines where a thinner oil would escape past the piston rings into the combustion chamber. The high viscosity makes it harder for the RESTORE CSL particles to circulate through the oil and we recommend using RESTORE Engine Restorer with a premium quality conventional motor oil of the grade originally recommended for your engine by the manufacturer.
Yes, RESTORE Engine Restorer can be used with Long-Life or Extended Life motor oils providing the engine is clean or cleaned and the oil filter changed before adding the fresh oil and the Engine Restorer. Long-Life motor oil manufacturers suggest it is possible to run your engine on the same oil for up to 20,000 miles before doing an oil change and whilst it may be true that the engine oil retains it's original qualities during that length of time, the engine oil can still become 'out of spec' due to particulate dirt, contaminants and metal fall-out in the oil.
If you are using Long-Life oils in your engine, do not neglect to change the oil filter on a regular basis (at least every 7500 miles) to remove debris and to keep the engine oil clean and healthy. Oil filters left in the engine beyond their intended life span will not only function poorly, leading to blockages in oil-ways, regulators and sensors, but may actually disintegrate. Paper filter elements often self destruct at 12-15,000 miles leading to oil-way blockages and noisy tappets that do NOT respond to flushing nor RESTORE. In this case, it may be necessary to carry out multiple oil changes to try to dislodge the paper fibres or else remove the cylinder head and direct an airline down the oil-ways to blow out the fibres or turn the engine over with a full sump of oil and the cylinder head removed, so the oil pump dislodges the paper fibres. The best prevention for stubborn tappet noise and oil starvation to the camshaft is to CHANGE THE OIL and FILTER EVERY 6 MONTHS OR 6,000 MILES max,. There are thousands of turbo failures every year due to over-extended 20k+ oil change intervals.
We advise against using RESTORE Engine Restorer together with additives that modify the viscosity of the engine oil (oil thickeners or stabilisers), 'Stop Smoke' products (oil thickeners containing resins), friction reducers (chlorinated paraffins such as Prolong or Activ8) or other oil additives containing particulate materials (e.g. Slick 50 (PTFE), Molyslip, Xado or Ceramizer). If you have used other additives in the engine recently it is advisable to flush the engine or to carry out an extra oil change before adding RESTORE. 'Stop Leak' products, which rejuvenate rubber seals to prevent leaks, are generally compatible with RESTORE Engine Restorer.
? Yes, RESTORE can be used in diesel engines with either direct injection or common rail fuel injection systems, with the exception of HEUI engines (see Engines that cannot use Restore below).
HEUI engines were designed by Caterpillar to deliver much better fuel economy in larger diesel engines and this is one of the selling points of a vehicle with a HEUI engine. In a normal Common Rail diesel engine, the whole fuel line is subjected to high pressure and the injectors are actuated mechanically by extra lobes mounted on the camshaft, with fuel pressure and rate of delivery to the injectors being entirely dependant on camshaft speed. In a HEUI engine, fuel delivery is governed by an ECM (Electronic Control Module). The ECM controls the amount of fuel delivered to the injectors, while a high pressure oil pump pumps the engine oil at pressures up to 4000 psi. The pressurized engine oil fires the injectors at the necessary rate to produce the optimum use of fuel for the engine load and vehicle speed, maximizing fuel economy and minimizing emissions. The HEUI engine was used in Ford Powerstroke and Navistar trucks, in the Isuzu Trooper 3.0 litre DTI dohc (1998 & on - engine prefix 4JX1) and also in some International trucks, Caterpillar equipment and other heavy vehicles with Caterpillar engines. This is not the sort of diesel engine you would find fitted to your average family car. A HEUI engine has two oil filters. If in any doubt, please contact your dealer.
Yes, RESTORE Engine Restorer can be used beneficially in a multi-fuel or hybrid engine (not 2 stroke petroil).
Yes, RESTORE Engine Restorer is equally effective in a fuel injection engine.
RESTORE is safe to use in most VVT engines (EXCEPT VVT-Li, iVTec or BMW Vanos or Valvetronic engines ..... see 'What other engines cannot use Restore?' below) provided that those engines do NOT utilise high pressure engine oil to actuate or regulate the VVT functions. All VVT units rely on clean oil of the correct spec to provide adequate lubrication and to function correctly and engine sensors are programmed to detect changes in oil viscosity that might suggest dirt, metal debris or contaminants in the oil that could clog oil-ways, contaminate solenoids and cause valve timing to malfunction. If you want to use RESTORE in a Standard VVT engine, clean the engine well beforehand using a proprietary flushing oil before refilling with fresh oil of the correct specification and fitting a new OEM oil filter. As an extra precaution, you can feed Engine Restorer into these engines slowly over the course of 30 minutes to 1 hour at tick-over to allow the CSL particles to circulate freely without overwhelming the narrow oil passages in these engines. If you are unsure whether your engine uses engine oil as a hydraulic fluid to actuate the VVT, call your main dealer for verification before adding RESTORE or call our technical helpline on 01728 726620.
Yes, RESTORE Engine Restorer is equally effective in Wankel rotary engines such as those fitted in Mazda RX7s and RX8s. One 400ml can is all that is needed to improve low compression and hot starting problems. Simply add to the engine oil.
Yes, RESTORE Engine Restorer is safe to use in vehicles with turbo-chargers or catalytic converters.
Yes, RESTORE Engine Restorer can be used as long as the engines are 4 stroke engines. When adding RESTORE to small engines such as lawnmowers, add 10% RESTORE by volume when changing the oil. Be careful not to overfill the crankcase since you'll need to add less motor oil to compensate for adding RESTORE.
No, RESTORE Engine Restorer is not formulated for use in 2 stroke engines using a petrol/oil mix, but it can be introduced down the spark-plug hole with the piston half-way down the bore. You can also use RESTORE Engine Restorer in 2 strokes where the oil is contained in a separate reservoir. Most modern scooters (Piaggio, Aprilia, Yamaha, Sym etc.) have a separate oil reservoir and all you do is pour 125ml into a full tank of oil.
Engine Restorer should not be used in any engine using engine oil as a hydraulic fluid, pumping it at high pressure to regulate or actuate other engine functions. The HEUI diesel engine is one of these. Although rare in the UK, HEUI engines are found in Ford Power Stroke and Navistar engines, some International and Caterpillar brand truck engines and some Isuzu Troopers (4JX1 engines). A HEUI engine is a high efficiency diesel engine where the injectors operate off engine oil pumped at high pressure – DO NOT USE RESTORE IN THIS ENGINE. A HEUI engine has two oil filters. If you are in any doubt as to whether yours is a HEUI engine, please ask your dealer before using RESTORE or call our technical helpline on 01728 726620
Many later model VVTi engines such as BMW VANOS or Valvetronic engines (incl. BMW Mini petrol engines), Subaru AVCS, Honda VTec and iVTec, Fiat MultiAir , Toyota Dual VVTi and VVTL-I engines, GM Active Fuel Management engines (fitted in some Chevrolet trucks but rare in the UK) and others, too many to list here, use high pressure engine oil to regulate camshaft positioning and valve timings. These engines rely heavily on clean oil of the correct viscosity as specified in the vehicle handbook and do not tolerate particles in the oil. Degraded, dirty engine oil containing sludge and swarf engine metal can cause the oil viscosity to go outside a narrow range programmed into the ECM; sensors detect the change in viscosity and trigger an engine management code, engine light and cause the engine to run erratically. For this reason, we DO NOT recommend adding RESTORE to the engine oil in any engine utilizing high pressure oil to regulate or actuate other engine functions. Please call our technical helpline on 01728 726620 for further information on how to treat these engines.
RESTORE should be added to clean oil in a clean engine. For best results, clean the engine using a proprietary flushing oil before changing the oil, refilling with fresh engine oil of the correct specification for your engine and fitting a new OEM oil filter. Then add RESTORE to the new oil. To avoid overfilling, make sure to reduce the amount of oil that you would normally use by at least the volume of RESTORE being added and then top up the oil using the dipstick to get a correct oil level. After 1000 miles or 20 hours driving RESTORE will have done its job but can be safely left in the engine till the next oil change.
Yes, they are extremely small and specifically manufactured to pass through the oil filter. Each CSL particle is spheroidal in shape and average less than 10 microns in diameter which allows them to pass through the oil filter and circulate through the engine along with the motor oil.
For best results, yes. Engines build up sludge over time from the by-products of combustion mixed with old burnt oil. RESTORE Engine Restorer contains mild detergents to keep the engine clean and corrosion free during and after treatment, but in a neglected engine the cleaners might release sludge allowing it to circulate and possibly block an oil-way. Sludge in your engine can only do harm. If your engine has been poorly maintained, cleaning it with a mild flushing agent (or ideally, automatic transmission fluid) will dissolve varnishes and gums and release all this sludge which will get caught in the oil filter. Change the filter before using RESTORE. The RESTORE CSL® particles will adhere more firmly to clean metal giving longer lasting results.
Badly neglected engines may need flushing twice or multiple oil changes to be sure of ridding the engine of free-floating contaminants. Make sure you change the oil filter each time too to catch the sludge released.
It is possible to add RESTORE Engine Restorer as a top up to existing oil in a well maintained engine with a minimal amount of sludge providing you fit a new oil filter to catch any sludge released by the detergents. If the oil filter gets blocked you will see a flickering red oil light. Change the filter as often as needed to keep pace with the sludge until the light stops flickering.
We do not recommend back-flushing using power flushing equipment.
By the time you’ve done 1000 miles with RESTORE Engine Restorer in the engine, the wear reversal process should be completed. Sometimes it takes a little longer and sometimes results are seen very quickly indeed; each engine responds differently, but certainly RESTORE will have done all it can do within 3000 miles or by the next oil change. Any unused RESTORE CSL particles will keep on circulating round the engine filling scratched and worn surfaces where they occur until the next oil change. Generally speaking, the benefits last for about 12,000 miles, but this will depend on driving style and use. It is recommended to add 5% RESTORE Engine Restorer by volume to engine oil once a year, or if you prefer at each oil change, to keep the wear under control.
The recommended measure is one 250 ml can of RESTORE Engine Restorer for every litre of engine capacity, e.g. a 1000cc engine (small car) needs 1 x 250ml can; a 2000cc engine (family saloon or Land Rover) needs 2 x 250ml cans; a 4000cc engine (large car or truck) needs 4 x 250ml cans or a one litre can. Alternatively, you can use 10% RESTORE by volume to engine oil in the sump as a 'rule of thumb'. However, after the initial application of RESTORE Engine Restorer at this recommended level, a 5% volume of RESTORE in your engine at each oil change should be sufficient to keep your engine protected against future wear.
Within a thousand miles of engine use and without having to disassemble the engine, you should experience a dramatic increase in ease of starting, power and torque, improved fuel consumption, reduced oil burn and lower smoke levels.
RESTORE Engine Restorer puts metal back into scratches cut into friction-producing metal-on-metal surfaces in the engine. It uses the reciprocating and rotating actions of friction-producing components to grind the spherical CSL particles into the scratches as they pass between. If your engine problem has not improved within 1000 miles of use, then wear in the metal is unlikely to be the cause of your engine problem. If there is still a noise, smoke or compression problem then have your mechanic look for something broken: cracked piston, broken rings, burnt valves, worn guides and seals, blocked PCV or stuck EGR etc. or call us for advice 01728 726620.
RESTORE Engine Restorer can be used in a manual gearbox or conventional (standard) differential, but NOT in automatics or limited slip diffs where it would make the clutch packs slip. The amount to use would depend on the size of the gearbox, but as a general rule of thumb 5% by volume of RESTORE Engine Restorer to gearbox oil would be sufficient. So for a small gearbox holding about 1 litre of oil, use 50ml (about an egg-cupful) of RESTORE, for a larger gearbox using 5 litres of gearbox oil, use a 250ml can of RESTORE, and so on. RESTORE won't be able to reverse wear on the teeth of the gears, as the gear metal is too hard, but will reverse wear in the bushings and ensure better engagement of the gear teeth, which will help tighten up sloppy gears and reduce whine and chattering.
