Oil and Filter Service: Car Manufactures are recommending oil and filter changes at 6,000 to 8,000 miles. At Wasabi Racing, we recommend changes every 3,000 miles for severe driving conditions. Due to oil contamination caused by gasoline and moisture residue from the combustion process, we consider even driving around town (repetitive short trips) to be severe. Changing your oil and filter often removes contaminan's thus prolonging your Engine's life.
