Choice of oil depends on a number of factors. Type of engine, gasoline or diesel, and if turbocharged. Also the type of service eg heavy work or just normal city or country driving. The ambient temperature must also be considered. For Thailand and neighbouring countries this is normally warm to hot. For Thailand higher viscosity mono and multigrade oils are most popular eg. SAE 40, SAE 15W-40 and SAE 20W-50. • For high performance gasoline engines, fully and semi synthetic oils are best.

Crane Cams does not recommend the use of synthetic oils during the initial break-in period for a new camshaft. Use a good quality grade of naturally formulated motor oil during this period. If you choose to use synthetic oil after the engine has been broken in, change the oil filter and follow the oil manufacturer's instructions. See similar questions...

No, Crane Cams does not recommend the use of oil restrictors. The oil is the life blood of the engine, not only lubricating but cooling the engine components as well. For example, a valve spring builds in temperature as it compresses and relaxes. This increase of temperature affects the characteristics of the spring material, and if excessive, will shorten the life of the spring. Oil is the only means the spring has for cooling.

Yes, there is no harm in using a Synthetic blend or a full synthetic oil. There are many benifits to using a synthetic engine oil, such as ease of starting, lower operating temperature, and reduced component wear. For more information, visit the Mobil 1 site See similar questions...

Use what the engine manufacturer recommends. Be aware that Kawasaki ® still recommends straight 30-weight oil in their engines, and Kohler Command™ engines require multiweight 10W-30 oil. The man who hired me here at Exmark, over 15 years ago, always said "the cheapest thing you will ever put in that engine is oil. See similar questions...

No, synthetic oils have shown no advantages when used and in some cases have actually harmed engines used in boating applications. See similar questions...

North America: Most vehicles have an emissions decal placed either on the backside of the hood, on the radiator core support, or on the air box (the box that holds the air filter in place). Your engine size should be shown on the decal (4.0L for example). If you can't find the emissions decal you may also find the engine size printed on the decal under the hood that shows your engine's belt routing. See similar questions...

All engines do burn oil, which is emitted again through the exhaust. The cylinders are oil-wet, fuel is burned, and so it burns the oil on the cylinder walls too. It's a simple as that. When it burns 1 litre every 1500 km you can start to worry, and when it burns one litre every 1000 km, the oil seal piston and/or cylinder is worn (one or all four). It goes the other way around too. The fuel/air/oil mix leaks a bit (due to the compression pressure) down into the engine/sump via the piston rings. See similar questions...

Fully synthetic Castrol TWS Motorsport 10W-60 Synthetic, and Castrol Formula RS 10W-60 Synthetic Oils. This is not readily available at your local WalMart. At this time its only available via BMW dealers and a few on-line retailers. Absolutely. The M3's computer is adaptive and will advance or retard ignition and make other adjustments depending on your fuel. The higher the octane the better (e.g. more power). Having bought a $50K+ car, this is really not the place to skimp. See similar questions...

A - It really depends on what you want. Both are the same. But PetroMoly? Oil Treatment is concentrated, and can be added to your favorite brand of motor oil. PetroMoly? Engine oil is blended by us, using the very best base oil and detergent package available, but it requires an oil change. See similar questions...

superheated oil exiting the turbo bearings sometimes looks like a chocolate mousse. this is why the turbos have a water jacket to help cool them. a turbocharger puts extreme stress on oil, and the oil is the only thing in your engine separating metal-to-metal disaster. again, bargain basement or generic brand oil is not a wise idea.

Imperial Oil does not recommend it. According to the American Petroleum Institute (API) and Alliance of Automobile Manufacturers (AAM), “certified oils eliminate the need for supplemental engine-oil additives.” In fact, the use of any oil supplement is not recommended by car manufacturers and may void a warranty. Considering the comprehensive testing and engineering that has gone into Mobil 1, nothing can be gained by using these supplements. See similar questions...

In most cases, we recommend a 10W30 motor oil. Refer to your engine operator’s manual for more specific recommendations. See similar questions...

Gasoline and diesel engines operate according to different engineering principles and burn completely different fuels. Gasoline engines require a volatile, high octane fuel whereas diesel engines run on a low octane and relatively low volatility fuel. Gasoline engines usually operate at higher temperatures and because of their composition and the high temperatures produce entirely different combustion products than does diesel fuel operation.

Caterpillar recommends the use of a multi-grade oil in all of its on-highway truck engines. Multi-grade oils are blended in two viscosity grades: SAE 10w30 and SAE 15w40. Use of these oils provide the correct viscosity for a broad range of operating temperatures and for cold engine starts. Find out more about Caterpillar lubricants. See similar questions...

Modern engine oils and fuels are carefully formulated to offer the best possible performance over a wide range of operating condition. There are occasions where an additive not contained in the oil or fuel will improve performance in one respect or another. However, there are also additives that will cause harm to the system. If aftermarket additives are used they should be thoroughly tested and offer more proof of performance than simple testimonial letters or anecdotal evidence. See similar questions...
