Valvoline Restore & Protect 完全合成 5W-30 モーターオイル 1クォート

Too soon to say whether its cleaning inside as it suggests 4 oil changes to show the effect. But the oil definitely made the engine noticeably quieter, smoother, and reduced the fluctuating revs I had due to the sludge (which I am hoping to clean by this oil). So its definitely effective in getting control of the internal lubrication requirements.

I used this oil in my snowblower and have been happy with the performance so far. The engine runs smoothly, starts easily in colder weather, and seems a bit quieter compared to older oil I was using before.The bottle pours cleanly without making a mess, and the oil itself feels like a quality synthetic product. I also like the added protection and cleaning claims for older engines.Valvoline has always been a reliable brand in my experience, and this seems like a very good option for seasonal equipment and regular vehicle maintenance alike.Overall, a quality full synthetic oil that performs well and gives good peace of mind.

Item as described, exactly what my equipment called for

I really want to believe this works but didn't really see a noticeable difference, worked well as any other motor oil. I'm not an experienced car person but I did notice it ran more quietly in the cold weather, which I can only count as an improvement. One thing I was kind of irritated by that I didn't see advertised on the bottle is that you're not supposed to use this with any other kind of motor oil. Take it with a grain of salt but, According to my mechanic mixing this with regular motor oil can damage your car. I really feel like if this is true it should be stated very boldly on the bottle so you can't miss it. Could also be my mechanic trying talk me into a more expensive oil change using this oil.All in all, I really want this to work and restore old parts better, but I think it's pretty overpriced unless it really does work

This stuff is legit! I've used it on my 2016 Honda Pilot and my 2016 Hyundai Elantra GT. Valvoline advises it takes 4 oil changes to really see the full difference. They're right - I'm on my 5th oil change for each car and these engines are "stealth" and quiet. No ticking and no slapping - just the quiet purr of a happy engine.
