Engine oil VALVOLINE or RAVENOL

Just threw some into my Corolla with around 200k on it. Always used standard 5/0W-20s in it and last time I was inside of it there was some light depositing and varnish, nothing crazy but it runs like a well-kept 200k mile engine. Seems to have alleviated a little bit of lifter tick in the 500-700 miles that it’s been in there so far. Seems like a good and high quality oil overall.

My Xterra would burn about 1.5 qts of oil between changes (I change every 3750 miles). Been using this stuff for about 18 months now and my oil consumption has gone down to just about 1/2 qt between changes, and my fuel economy has improved by about 1-2 mpg.

Legit! I’ve had great success with this oil. Eliminated tap, removed a ton of sludge from my engine(previous owner didn’t take care of car) and overall better performance and better gas mileage. I’ve done 9 oil changes since I switched to this oil and it has done wonders. When I first got the car, when I would change the oil, within 500 miles the oil on dipstick was dark as hell. Now after 9 oil changes the oil stays clear(ish) up to 3000 miles. And it has significantly reduced oil burn. I swear by this oil and I tell everyone I know about it. It’s not a gimmick! It really works!

I've seen good results online.

For 2 dollars more than the regular high mileage offering, I figured it was worth the risk.

I am doing a couple of oil changes with it (1k, 2.5k, 5k), and am hoping to see some evidence of it working on my 190k Mazda 3.

I have finished 1 oil change at 4k miles on a 2014 impreza that the previous owner religiously changed at 8k miles with cheap oil and cheap filters. My MPG improved a little and oil consumption went from 1 qt every 1k miles to 1 qt at 3k miles. I also commute 54 miles daily so the oil wasnt in the car that long. I "feel" like its doing something.

Running it in my Subaru outback 2.5 with 50k miles. I noticed a difference in the first 1k miles.

Better compression and better mileage (2 to 3 mpg!) a lot quieter!

Also running it in Subaru outback 2.4 turbo with 30k miles. A bit better. Not huge. But noticing.

Also a lot quieter!

Nah. I have a 2006 Merc 4.0. 183K. I run high mileage Valvoline 10W-30 oil. My Merc does not burn oil. Runs great.

Valvoline Restore and Protect. This newly designed oil can, and does, remove up to 100% of engine deposits. Including those found on and around the piston rings. A major contributing factor to oil blow-by, or general usage between oil changes. It take a couple 4k mile oil changes to work. Everything I have researched shows that it does work and many, most even, report a significant reduction in burning oil between oil changes, but do your own research! :) I wasn't having oil burning issues in my 8th gen, but still ran it through a couple times because it certainly won't hurt anything!

So I had this same question because I assumed that my local Toyota stealership would use “Toyota” brand oil, especially since they charged $70. Come to find out they used Valvoline.

I was planning to but returned it. It was listed as a GL4 oil on the website but when it arrived, there wasn’t a mention of the GL4 on the bottle. Had a look at a technical spec sheet of the product online and it isn’t a GL4 oil indeed. Ravenol is quality oil however
