As the Valvoline VR-1 is synthetic, no crude oil was used in its making. Like most synthetic oils, the oil gives much better mechanical performance than traditional motor oils made from crude oil. 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. With all the talk lately about roller lifters and oils...as well as flat tappet cam failure....I found this testing by Valvoline to be pretty interesting too. A product we invented over 150 years ago, and one we have been reinventing ever since. The Valvoline™ family of motor oil has a formula perfect for your vehicle’s needs. Search through our wide range of options to find the best motor oil for your vehicle. Like any other product, there are other competing oils for your racing car in the market. Its major contender is none other than an oil from its own range of racing lubricants, the Valvoline 10W-30 VR1 racing motor oil.

Synthetic motor oils are inherently more stable and less prone to thermal breakdown vs. conventional oils. Meanwhile, for race cars, Valvoline VR1 should be changed after every 500 miles. Racecar engines have high RPM, and oil consumption is higher as compared to regular car engines. Therefore, it is best to change the oil once it has reached, or is about to reach the 500-mile threshold.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." 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 vs synthetic engine oil. For now, you should bear in mind that if you are planning to use Valvoline VR1 racing oil, make sure 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.

As engines age past 75,000 miles, parts begin to wear down causing reduced gas mileage, lower horsepower, and a shorter engine life. That's why we created Valvoline High Mileage motor oils formulated specifically to combat issues like friction, deposits and sludge in aging engines. The oil also helps increase your vehicle gas mileage while reducing unnecessary engine wear at extremely high and low temperatures. However, as synthetic oil is derived through a complicated production method, the oil costs more than conventional motor oils. Tailored for gasoline and full or partial alcohol fuelsValvoline 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. The unique sapphire blue coloured oil is specially formulated to bring out the best in your engine by minimising the formation of deposits and friction and increasing horsepower. Besides, the oil is protected against extreme stress by its defoamer and its low viscosity levels easily starts your car in cold temperatures. Comparison

Valvoline offers a full range of specialty engine lubricants and cleaners to help keep your engine at peak performance. Get answers from Valvoline for FAQs about motorcycle and ATV motor oil, such as Valvoline compatibility with Harleys, if ATV oil meets service classifications and more.Oils meeting ILSAC GF-4 requirements (usually 0W-20, 0W-30, 5W-20, 5W-30 and 10W-30 SM oils) cannot have the following restrictions on phosphorus and sulfur:

Within the race engine oil category, Valvoline VR1 tends to perform better because of the boosted levels of Zinc and Phosphorous. Both of these chemicals act as antiwear compounds in synthetic engine oil. As a result, the engine’s performance is boosted to above optimalNever 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. engine. If there is a difference, the resultant effect will most likely cause the engine to malfunction. happen. At best, the engine oil will cease to perform and acquire the shape of solid sludge. As a result, the car engine’s RPM will be I had similar concerns about the current SM oils being sold so I inquired to the API tech line and this is what I found.
