where is the cheapest place to buy stanadyne additive thanks
I have used stanadyne performance formula,and primrose 405 and (409 winter formula )since my truck was new and been happy with both. My truck has 32,000 miles on the OD,so far so good,no injectors problems yet. Fingers are crossed. Some folks don,t believe you need a additive,some folks do. Personal perference I guess. coobie. Oo.wmoody said:just curious what makes stanadyne so good, or is it a preference thing?![]()
