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.

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

The BMW manual recommends BMW 5W-30 High Performance Synthetic Oil, Castrol/Mobil 1/Valvoline SynTech synthetic, and allows use of other synthetics provided they meet the specification API SH or higher. If you open up the hood, you will see a cap labeled "25 nm" near the front of the car staring up at you. Unscrew it and you will find the filter. You should always buy an OEM oil filter from your BMW dealer. It will come with a required O-ring. See similar questions...

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...

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. 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...

Not very important at all. Unfortunately, due to ?a**e covering? reasons we cannot print this advice on the can! Although officially all manufacturers advise against mixing different makes and grades, in fact there is very little chance of any harm being done, even if one is a mineral 20W/50 and the other is a 5W/30 synthetic. Obviously, avoid this if you can, but do not panic if there?s no other alternative. See similar questions...

turbocharged car owners generally favor pure synthetic or synthetic blend oils over dino oils. synthetics' shear and anticoking properties at high temperatures are ideal for protecting turbocharged engines. any synthetic of the proper weight will do. don't get hung up on brand names. if your tt has a new engine or fresh short block, allow 5,000 miles for break-in with dinosaur (mineral) oil before changing over to synthetic oil. the "dino oil" helps seat rings, seals, etc. 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...

Some of the larger particles of the Microlon resin may not pass through the Frantz-type oil filter. This Frantz-type cartridge must be removed or by-passed during the treatment period to avoid a possible loss of some of the particulate. Nothing in the Microlon treatment is larger than 5 microns, however. See similar questions...
