You should search for the Lucas write up someone did here,it is in the threads if ya search,bet you won't use it too much longer.........IMHO there is a lot better products out there....i have used lucas in every vehicle i have owned,and also all my equipment,even my toys and (knock on wood) and have never had an engine issue and i usually drive them 200k miles
You should check Tractor Supply then, I usually find it for the same price if not a few cants cheaperAs much as I hate walmart/sams, I am heading to sam's club in a little while to buy some rotella. They had the 2 2.5 gallon jugs for 50 bucks. $10/gallon. :rockin
If I ever removed my emissions crap I'll go back to synthetic.
