Used Ams Oil top of the line signature synthetic for years Did not live up to its promise. Burned out my turbo with normal use. Nothing excessive. Just highway driving, frequently. Need car to get to work, so no abuses. No track activities, or the like. Tried Can Royal 5 W 30 mfg recommended weight, worked great! Fast spool up on turbo, very smooth running. Will switch over.

I recently took my Honda Accord to a mechanic shop in order get an oil change. When I went there, they recommended CanRoyal to me. Till this day, my car engine runs as smoothly as a babys bottom.

Great oil. I use this royal lubricant and its been great
