I have used it in several of our vehicles. I did not run UOA. Easy, quiet start ups in all weather conditions encountered. MPG was at least on par with the other synthetics we used,better then some but not a scientific type test. In fact my youngest sons vehicle is on it's third OCI running Lucas 5W-20 right now.
If you don't have a stash of sale or rebate oil,or mind spending a few extra dollars, go for it. IMO it is good stuff
