what kind? the really thick stuff or the pure synthetic which is thinner? Someone told me that the thicker stuff will mess with the injection system.

well it's thick tell it gets worm and you are mixing it with 14Q of oil it will thin out quick it's not thick for a long time BUT it is sticky which is good to prevent dry starts

Very true, but the lable specifically says to use the pure synthetic must be a reason, i just don't want to experiment with my truck and learn what that reason is the hard way.

There is another post from a few months ago that is very detailed on why it is harmful. Under very high preasures it gets foamy, which is bad for the injectors. I used to use it until I read that forum.
