Rated 1 out of 5 by CASTROL oil & its other products are, "in my opinion", the ONLY products to use in your engines, if you want them to last & keep your engine running!! As a mechanic for a lil over 30 trs, i,ve used "many" oils/filters/additives through those years. Besides being a mechanic, i,m also an "auotmotive machinist", where i have rebuilt MANY engines! Ohhhh, the stories i could tell you of the sludge build up/major wear of the cylinder bores, & the carbon buld up on the valves, & worn valve guides on the custemers engines i,ve rebuilt is endless!! Upon asking the owner what brand of oil they were using, i ALWAYS got the same reply---"ohhh what ever is cheapest"!!!! Bottom line------"use a TOP GRADE oil/filter like "CASTROL" & keep your enging running like new for years to come!!! TRUE/HONEST TESTIMONIAL!!!! GARY! October 8, 2014
