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.

Given the fact that literally thousands of fuel additives are offered on the market, engine manufacturers have no way of monitoring or testing the claims of so many products - making it difficult to determine specific products that are safe to use. However, PRI chemistry does not alter any fuel specifications issued by engine manufacturers - specifications by which manufacturers judge whether or not a particular fuel affects safe engine operation.

The only fuel additive that Indmar recommends is the use of Sta-Bil Fuel Stabilizer. Stabilization of fuel is required during off-season storage. We also recommend the regular use of Sta-Bil for boaters who don?t regularly burn a tank of fuel every week or two.

No. AMSOIL is a solo act. Everything your engine needs for lubrication and protection is in the oil. Additives can upset the oil's precise chemistry, or worse, interact with the oil in unpredictable and harmful ways. Save your money ... and your engine. Skip the additives.

this time the emergence of Bioheat® fuel is much too new for burner manufacturers to comment on. However, in work accomplished throughout the northeast, organizations like Carlin, Beckett and Power Flame (notable burner manufactures) all are reviewing Bioheat® fuel. Bioheat® fuel appears to have little or no negative impact on a burner’s performance while providing emissions, sulfur, lubricity, global warming and health benefits.

Yes. It has been proven that the Tadger will complement any type of additive or bio-diesel. The Tadgers' performance is enhanced as the quality of the fuel is enhanced.

There is a continual debate about what type of oil to put in your car. My own opinion is that, if you use a high-quality motor oil of the correct weight, it doesn’t matter which one you use. Some people advise against putting synthetic oils in VWs or Porsches. There is a myth that they do not dissipate heat as well as conventional "dinosaur" oils. This is untrue—some of them have tested out better than dino oils.

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.

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

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.

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.

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

Justice Brothers products can be used from the very first day of a new car or at any time on older vehicles. Justice Brother's oil additives will reduce engine wear and friction, but will not interfere with the "break-in" period of a new car. Yes, Justice Brothers Power Steering Conditioner & Treatment will correct squealing and hard spots and stop most seal leaks. The product is also good to use in new units to prevent wear.

For our Zenoah-powered boats, we recommend a 20:1 or 25:1 mixture of a quality 2 cycle synthetic oil. Zenoah recommends 90 or higher octane unleaded fuel (although we have quite a few customers who have had success with 87-89 octane). We recommend a mixture of 25:1 (5 oz of oil to 1 gal of gas) or 20:1 (6 oz of oil). Either will work for you, but you should pick one mixture and not change. The oil needs to be a good 2 stroke synthetic. We recommend AMSOIL.

In general, modern engine management systems will compensate for fuel octane, and once you have satisfied the optimum octane requirement, you are at the optimum overall performance area of the engine map. Tuning changes to obtain more power will probably adversely affect both fuel economy and emissions. Unless you have access to good diagnostic equipment that can ensure regulatory limits are complied with, it is likely that adjustments may be regarded as illegal tampering by local authorities.

It can be used in conjunction with other Rapid Set® Concrete Pharmacy® items or certain approved additives.

Anti-Oxidant - Reduces bulk oil oxidation which helps to prevent engine deposits, sludge, and high temperature thickening Detergents/Dispersants - Help maintain engine cleanliness by suspending sludge and wear particles in the oil, so that they can be rained out during oil change.
