Fingers = crossed but working on my Stag at present?
Tried this on my 1973 Triumph Stag V8 3l, blowing out to of left bank. Instruction 1 bottle for up to 2.5 l engine, on the basis that I am a bit of a miser and a 3l v8 is in reality 2x 1.5l, I tied it with just one bottle. A few months down the line with little use and it seems to have worked no more over heating and no more white smoke out of the left hand exhaust. Fingers crossed. Have bought another bottle to give a small top up.
