Rislone Hyper Lube Oil Supplement Automotive Additives, 32 oz

Great for older cars. This is prolong the life of your car.

I do not change oil as much. When I use this with my synthetic oil, my gas mileage average goes from 28 to 31 and my oil changes happen twice a year. My engine is quieter and along with Marvel Mystery oil, I swear it makes all engine components fire proof.

I use a half quart of this with every oil change on my car and truck both have high mileage. Always helps with dry startup where all of the wear usually comes from.

It is a great product for my slightly older vehicles. However, the product had leaked a bit in the box when I received it. It could have been packaged better.

Love this stuff. My car always runs a sounds great. Give it a try I think you'll like it. Got more expensive though since inflation but that's the fault of the current government. Not the product.

Helps to increase the viscosity rating of modern engine oil.

This product work well on oil change time U can fill 32oz in 4 cylinder vehicles Very good for engine in all weather

I was so impressed how quickly I received my order. When my order arrived, it was exactly, if not more, what I expected. Great experience.

I have tried many similar products like this "oil stabilizer" I have an older honda that smokes a little bit and if I mix a product like this in with the oil it helps a lot. This stuff is cheaper and seems to do a better job then say Lucas oil stabilizer. So I am happy with it.

Good product. WalMart shipping is terrible. This and a 5-qt jug of oil in a large box with very little padding. The Rislone leaked due to very poor packing by WalMart. Sent a complaint, though they do not care. They already have my money.
