Rated 5 out of 5 by Castrol castrol edge ful synthetic oil
I have been using castrol edge full synthetic and also the extended version in all my vehicles. My chevy truck with 6.0l which i use to tow and haul trailers as well as a secondary vehicle, I have been running castrol edge oil for about 2/3 its life. Well my truck has 312,000mi currently and runs like the day I bought it. Not even a slight tick comes from the motor, nothing at all it just purrs. Its also all original, never had any valves done or seals or anything, only battery, alternator, belt small things, and just did a water pump at 311,000. I also add lucas synthetic oil additive each change. Very Impressed, obviously the oil minimizes engine wear to a significant degree. I will continue using castrol edge and looking forward to seeing how any miles I get with my truck doing so. Also my other vehicles have much less mileage but motors love this oil, a Hemi 5.7 and 3.7 gm v6. Keep up the good work and quality Castrol..

Rated 5 out of 5 by FasterThanYou302 Top notch oil at a reasonable price!
I was always a user of Royal Purple synthetics in my vehicles because when I first got into racing back to back Dynos showed gains of almost 10 HP and 6-7 lb/ft TQ switching from Penzoil Classic to the Royal Purple synthetic. Well I did some more testing in the shop and Castrol Edge offers the exact same performance benefits as the Royal at nearly half the price per oil change. (DynoJet 248H- Test engine Chevy LS1 w/ported 243 heads, Fast LSX/90mm, DDTECH custom grind can, bolt-ons, stock bottom end with 130k-made 411whp/403wtq on 93 octane running this oil) Also after running 15,000 miles on Castrol I sent samples of my oil in from my daily driver and the tests came back perfect with my 130k mile engine showing absolutely no wear or abnormalities. Go Castrol Edge for your synthetic needs and don't look back.
