VALVOLINE VR1 20w/50 Racing Oil 5 Litres

Product Information

Also put it in a Briggs and Stratten air cooled 5hp engine about 5 years ago, the sees a lot of hot dirty conditions. Have never changed it or added and it still looks clean. I am waiting for a shipment of AmsOil to arrive for my HD and vette. My engine is not raced and has hydraulic lifters so not a race engine. I am only concerned with high temps that is a problem over here. Does anyone have experience with AmsOil ??S.Florida so temps are pretty high daily.

While buying any type of synthetic or non-synthetic engine oil, make sure that the API rating of the engine oil matches that of your car’s It seems that's where some of the confusion has come from, where API SM called for reduced zinc/phos, BUT then doesn't apply to certain types, even those that don't have the "starburst seal", but would still say SM rated, but with only the API doughnut symbol, etc. Geez, who's on first? Gets rather involved doesn't it? Alternatively, if you own a street-legal variant of a racing car, then go for the gray-colored bottle of Valvoline VR1 engine oil. This product description on this bottle mentions that the oil can be used on street-legal sports/ race cars for up to 3,000 Miles between average oil change intervals.

Valvoline offers a full range of specialty engine lubricants and cleaners to help keep your engine at peak performance. It would appear that a few things are getting cleared up, and that we are learning something, so that's good. engine. If there is a difference, the resultant effect will most likely cause the engine to malfunction.

Valvoline VR1 Racing is a 20w-50 mineral engine oil that’s formulated to deliver maximum engine performance in both turbocharged and non-turbo petrol engines. The unique chemistry of Valvoline’s VR1 Racing oil reduces harmful friction in the engine and enhances engine power, perfect for drivers seeking race-level performance that doesn’t compromise on protection. Although it’s one of the most popular engine oils for racing, Valvoline VR1 is also 100% compatible with passenger cars that take 20W-50 lubricant.Converters and Catalytic Converters, it is better to talk to a professional or someone who has experience with both engine types.

The latest API SM standard for car oils calls for a zinc and phosphorus content less than 0.08% to reduce sulfur, carbon monoxide, and hydrocarbon emissions (this contradicts what the Valvoline guy said about SM having nothing to do with zinc/phos).As a result of this mandate, some motor oils now have as little as 0.05% zinc and phosphorus and many of the motor oils we tested did not have the levels as found in, for example, Mobil 1. However, it is worth noting that these new API guidelines do not apply to “racing,” “severe duty,” or any motor oils that do not carry an API “starburst” seal or clearly state for off-road-use only. Motor oils meeting “Energy Conserving I or II” standards should be avoided." Unsurprisingly, such automotive beasts are powered by super-strong engines that are unlike their passenger car counterparts. Racing car motors produce extreme heat and pressure, as well as use more fuel due to the differences in power. In case you acted on the impulse and got carried away by the race engine oil hype, perhaps your mistake can be redeemed. It depends on how long you’ve had the oil left in there vs the current performance stats of your car’s engine. Valvoline stands behind the flat-tappet and more aggressive type cam applications 100% with our Valvoline VR1 and NSL Racing oils. The proof is in our product information sheets, which are online for the viewing as well.While the extra layer of Zinc and Phosphorous shield the engine against metal-on-metal damages, the oil also damages the catalytic Synthetic motor oils are inherently more stable and less prone to thermal breakdown vs. conventional oils. Never had to add in between filter changes and the engine was the only thing that was never touched in that vehicle. Still going strong with other owners AFAIK. Engine never apart so I couldn't really inspect parts. The worst thing that can happen to a racecar driver is to experience vehicle failure or malfunction. Such a predicament can end up affecting the seat time and leaving the driver weeks behind. And we can all agree that nobody likes to lose, especially if racing for profits. A combination of coverage from conventional and synthetic oil to help keep engines running like new.
