I do not have any experience with Shell Rotella.....I did try Valvoline's "Max-Life." I thought that perhaps an engine oil made for "Higher-Mileage" cars would be benificial to my 175,000 mile SC. After about 500 miles my car sprang oil leaks from every which point. Probably due to a high detergent content, not un-like synthetic oils. My recommendation is to stay with the type of oil that your car is used to. It appears that the seals on older cars do not seem to like high detergent oils after years of service with more traditional oils with less additives. After a rebuild and "all-new" gasket replacement, perhaps would be a time to change to synthetic or any other oil that has a bunch of additives. U may want to search threads on the subject...I did...But none on the "New-High milage formulas." I guess I was a guinnie-pig(SP)
