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.

Absolutely does what it says it does. Need to do a few oil changes for it to really work if you have neglect. I run 5w-30 in our 2017 coyotes and have been impressed. Has cut our oil consumption issues down

This is the hottest oil on the market. Cleans awesome. Dont believe me youtube it

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
