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 offers a full range of specialty engine lubricants and cleaners to help keep your engine at peak performance. 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.

CI-4 PLUS oils do not have a limit on ZDDP, so the amount in specific CI-4 PLUS oils depends on the additive treat used by the oil marketer. You can safely say that CI-4 PLUS oils have a fair amount of ZDDP. We do not disclose this information. One reason is that there are oil companies that strive on numbers alone and try to make it a numbers game. Well the problem we have with this is that the other oil companies could try and get the same numbers as we have even if their product does not have the same quality and performance gains as ours. This could make a customer think they are buying a great product based on the numbers. If all the numbers on the sheets are the same how would you decide on which oil to choose? Price? All I can tell you is our motor oil exceeds the levels for the API service SL and our MaxCycle and XPR are even beefier than that. Thank you for understanding. What application are you looking to protect? If it is a flat tappet cam or a high performance cam, you will be safe to run any of our oils. Here are the product information sheets with test results for all of VR1, Not Street Legal conventional, and Not Street Legal Synthetic. Valvoline High Mileage with Maxlife Technology is formulated specifically to combat issues like friction, deposits and sludge in aging engines. 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.This label means that the oil is specifically meant for race car engines. On that note, one single refill will last you about 450 – 500 miles The oil is specially formulated to control any friction in the engine when in use and the process improves the engine performance even in extreme service conditions. This is why the oil is today one of the reigning leaders in lubricants used for any type of racing including drag racing and dirt and paved ovals. Low viscosity There was a time when 75,000 miles meant that a car was about three-quarters of the way to the junkyard, but 200,000 is the new 100,000 miles for cars.

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. 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. 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. 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: 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.

Comparison

A combination of coverage from conventional and synthetic oil to help keep engines running like new. 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 Supersonic speed, impressive agility, and a high-performance engine are synonymous with racing vehicles. 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. Synthetic motor oils are inherently more stable and less prone to thermal breakdown vs. conventional oils.
