Product reviews for Archoil AR9100 Friction Modifier - 16oz

Heard alots on that product and it is pretty awesome. Took about 150-200 kms and the engine is way more quiet than before. The shipping from BCdiesel was really quick. Received it the next day morning. Look foward to order more stuff

I was experiencing slightly harder starts with my 2000 7.3L F350. I started noticing a significant improvement after a week or two of use (I don't drive much), more so than any other additive that I've tried so far. Highly recommended!
