Engine oil VALVOLINE or Shell

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.

We use rotella t-6 5-40. Have put on well over a million miles between our vans and its been good. 10k intervals. We have on a 2019 with 260k. Never had any issues. Still on our original DPF. So it's safe to it's low ash oil.

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!

Shell. Literally makes my vehicles dead silent after every oil change.

Currently on valvoline and it does seem good, not sure if it's better than the elf in the short run but long run could tell different results.

You can use it for motorcycles I have in the pass only thing I don't like is my bikes don't shift gears super smooth with rotella also in my Yamaha owners manual it says in capital letters do not use diesel oil and I did and I fried my clutch plates and had to put new clutch plates
