Yes, we offer two different two different oil products. In order to ensure that your fresh oil doesn’t immediately get contaminated with old deposits, we recommend using Berryman OIL CHANGE FLUSH (part #1216) immediately before changing the engine oil and filter. 1216 gently cleans deposit buildup using the same type of detergents and dispersants as those used in high-quality engine oils. That said, out of an abundance of caution, we still recommend on vehicles with excessive engine deposits, such as those with high mileage, sporadic maintenance, or lengthy oil change intervals that the user remove and clean oil pan and oil screen before replacing engine oil and filter.

Additionally, we offer BERRYMAN ENGINE OIL EXTENDER (part #1210), a super-premium engine oil additive designed to extend the life of all in-service engine oils. 1210 reduces friction and wear, helps prevent deposit formation, and provides start-up protection. Simply add the product to your crankcase when you’re about halfway into your regular oil change interval and then “reset the clock” on the oil. For conventional motor oils, we recommend adding it at 1,500-2,500 miles after last oil change and driving another 3,000-5,000 miles. For synthetic motor oils, we suggest using it 3,000-4,000 miles after last oil change and driving another 6,000-10,000 miles.

Best of all, both 1216 and 1210 are fully compatible with all single-grade and multi-grade, conventional and synthetic, gas and diesel engine oils and both products treat up to 6 quarts of oil.
