I have been reading up on redline 5w-20 and from some of the opinions here it is a very stout 20wt oil , actually some say it can be used in 5w-30 applications. My Chevy trailblazer is specd for 5w-30 but I have wondered how the redline 5w-20 would work in it . only issue I might have is that I tow my large bassboat in the spring and summer months.The truck does take 7 quarts so it is a little easier on oil that say a truck that would take only 5 quarts. Guess I could use it in the fall and winter ? my ride that I bought it for was just totaled and the new Honda is specd for 0w-20 so I do think really want to use the 5w-20 in a new car as it is really a 30wt oil.
