These converters are also installed in sports bikes that are above 600CC category. Now if you don’t know about Cam Here are the product information sheets with test results for all of VR1, Not Street Legal conventional, and Not Street Legal Synthetic.

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. 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? 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. 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.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. and that too if the car is used for actual racing. Otherwise, the catalytic converters are still going to get damaged if the car is 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 fuels Valvoline High Mileage with Maxlife Technology is formulated specifically to combat issues like friction, deposits and sludge in aging engines. 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.

So, let’s see how you can ensure that your racecar stays in top-notch condition throughout the season.

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. 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. 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."
