Engine Restore – Frequently Asked Questions

WHAT IS RESTORE AND WHY SHOULD I USE IT? 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.

HOW DOES RESTORE WORK? RESTORE 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.

WHAT ARE THE BENEFITS OF USING RESTORE? By using 10% RESTORE as an initial 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, better acceleration and it will run smoother because the compression is balanced across all cylinders. In addition, if your engine is burning oil and smoking because of blow-by and piston-slap, RESTORE will reduce and improve this situation.

IS RESTORE GOOD FOR MY ENGINE? Yes, RESTORE is an extreme pressure lubricant in its own right, but it also reverses engine wear, providing there are no friction-reducers in the oil e.g. Slick 50, Prolong, Activ8, Motorup, STP and Wynn’s friction-reducers, PTFE, Teflon, Chlorine, Moly and the new range of plant Esters such as Magnatec, and Silkolene R racing oils which contain positively charged particles which stick to metals. This kind of oil or additive will work against RESTORE being successful. If you have had friction-reducers in your engine recently, it’s best to flush the engine before using RESTORE. However, once RESTORE has worked its magic you can go back to your normal additive if you wish (see below ‘When should Restore be added to engine oil’)..

IS RESTORE SAFE TO USE IN MY ENGINE? Yes, RESTORE is an EP lubricant that enhances lubrication of your engine. That means better protection against engine wear than you can get from using plain motor oil or motor oil containing other types of additives. In addition, RESTORE cleans inside the engine to remove dirt & sludge buildup and with regular use keeps your engine clean.

It is important to note that RESTORE does not contain polytetrafluoroethylene (PTFE), zinc dialkyldithiophosphate (ZDDP), chlorinated paraffins, naphthalene, xylene, acetone, isopropanol, sulphur compounds, or any other chemicals which could potentially harm the engine.

IS RESTORE COMPATIBLE WITH SYNTHETIC OIL? Yes, RESTORE may be used with any type of inexpensive mineral or synthetic motor oil such as those available on any supermarket shelf. In other words, use plain oil with RESTORE (no friction-reducing additives)..

DOES RESTORE INCREASE THE MOTOR OIL VISCOSITY? No, RESTORE does not change the viscosity of the motor oil.

WHAT ABOUT USING RESTORE WITH "HIGH-MILEAGE" MOTOR OILS? Those types of motor oils are simply higher viscosity oil that cost more money. We recommend using a premium quality conventional motor oil..

CAN RESTORE BE USED IN DIESEL ENGINES? Yes, RESTORE can be used in diesel engines. We recommend using RESTORE in any 'common rail' fuel injection system engine with one exception: RESTORE MUST NOT be used in HEUI fuel system diesel engines such as those fitted in Ford Powerstroke and Navistar truck engines, some Caterpillar vehicles and plant and machinery with Caterpillar engines, some International brand truck engines and some Isuzu Troopers. A HEUI engine is a Caterpillar® designed high efficiency diesel engine where the injectors operate off engine oil pumped at high pressure – if you are in any doubt as to whether yours is a HEUI engine, please ask your dealer before using RESTORE.

HOW DO I KNOW IF MY CAR HAS A HEUI ENGINE? 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. If in any doubt, please contact your dealer. More information about the HEUI engine.....

CAN RESTORE BE USED IN VEHICLES WITH TURBOCHARGERS OR CATALYTIC CONVERTERS? Yes, RESTORE is safe to use in vehicles with turbo-chargers or catalytic converters.

CAN RESTORE BE USED IN LAWNMOWERS AND TRACTOR ENGINES? Yes, RESTORE 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.

CAN RESTORE BE USED IN 2 STROKE ENGINES WHERE OIL IS MIXED WITH PETROL? No, RESTORE is not formulated for use in 2 stroke engines using a petroil mix, but it can be introduced down the spark-plug hole with the piston half-way down the bore. (Please refer to the attached Instructions to 2 Stroke and 4 Stroke and wet clutch users). You can also use RESTORE 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.

WHEN SHOULD RESTORE BE ADDED TO THE ENGINE OIL? For best results, RESTORE should be added when changing the oil & filter. For even better results, flush the engine with a mild flushing agent (automatic transmission fluid is ideal), fit a cheap oil filter to catch all the sludge and then change the oil and filter again, this time using a quality filter, the recommended oil and adding RESTORE. To avoid overfilling, make sure to reduce the amount of oil that you would normally add by about a pint (500 ml), add RESTORE and then top up using the dipstick to get a correct oil level. After 1000 miles or 20 hours driving RESTORE will have done its job and you can either leave it in the oil until the next oil change, or if you wish you can change the oil a third time and then add in your normal friction-reducing package.

DO I NEED TO FLUSH MY ENGINE (4 STROKE ENGINES PETROL AND DIESEL)? For best results, yes. Engines build up sludge over time from the by-products of combustion mixed with old burnt oil. If your engine has been poorly maintained, cleaning it with a mild flushing agent (or ideally, automatic transmission fluid) will release all this sludge which will get caught in the oil filter. Change the filter before using RESTORE. We do not recommend back-flushing using power flushing equipment.

RESTORE is not a substitute for good regular oil changes and factory recommended oil change intervals and maintenance procedures. However, RESTORE does contain a mild cleaning agent which will clean a well maintained engine before the CSL metal particles can do their job at repairing the engine. So it is possible to add RESTORE as a top up, knowing that a well maintained engine will have a minimal amount of sludge and the existing filter will be able to keep up with the sludge. If the filter gets blocked you will see a flickering oil light. Change the filter as often as needed to keep pace with the sludge until RESTORE can reverse the wear. After 1000 miles, RESTORE has re-metalized the engine and you can change the oil and filter and go back to using whatever oil package you have been doing. RESTORE has done its job. If there is a still a remaining smoke or compression problem then have your mechanic look for something broken: piston cracked, piston rings broken, burnt valves and worn guides and seals, blocked PCV (pressure control valve controls excess pressure in the crankcase) or EGR (stuck exhaust gas recycling valve will allow the engine to smoke) etc.

How long does restore last? A noticeable difference in engine performance should be experienced after 500 miles. By the time you’ve done 1000 miles with RESTORE in the engine, the wear reversal process should be completed, but unused RESTORE 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 by volume to engine oil once a year, or if you prefer at each oil change, to keep the wear under control.

HOW MUCH RESTORE SHOULD I USE? The recommended measure is one 250 ml can of RESTORE 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 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.

Can I use RESTORE in fuel injection engines? Yes, RESTORE is equally effective with a fuel injection engine, but must not be used in HEUI (Hydraulically Actuated Electronic Unit Injection) diesel engines, where the injectors work off engine oil pumped at extremely high pressure.

Can I use RESTORE in a multi-fuel vehicle? Yes, RESTORE can be used beneficially in a multi-fuel engine (not 2 stroke petroil).

CAN RESTORE BE USED IN GEARBOXES? RESTORE can be used in a manual gearbox or conventional 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 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.
