Do what Cary says but send it to me for "testing"
in my daughters cars !!!
Kev99sl, seriously your machine will really like using these oils. What kind of car/engine ?
I do recommend a 1500 mile Auto-RX precleaning before using as the RL oils will attempt to clean the 1000's of miles of deposits in the engine.
So you don't deplete the lubricating benefits of the RL oils by chemically coercing them to clean.
