Mag 1 61788 Full Synthetic SAE 10W-30 Motor Oil - 1 Quart

I have no objective way of telling if this oil is any good. I've used it on all my cars for the past few years and none of their engines have blown up or seized. The only thing I can tell is that it meets certain API specifications. But then again all motor oil does. I wish I could say I get longer engine life or better gas mileage but that would take studying a large data set comparing many cars over a few years of time. It seems to stay clean looking for a longer time. Oh....and it's priced well which is probably my main reason for using it.

Changed my oil with this after using an engine flush. This replaces my castrol edge synthetic oil that was in my 2005 toyota corolla after 6000 miles, my usual oil change interval. Bought this because it was a great price. It seems to be working good no problems. After 500 miles no oil consumption, Still have a unused quart remaining after filling up the engine to the correct level, all this for the same cost of the castrol minus the extra quart.........

Good price for the quality and quantity, they know how to put price on this one, because is right on the price. if they are going to increase. it I will go the costco for mobil 1 which they have sale for pack 6 $29 bucks or walmart for one gallon jar. Hey lets put it this way Im not a brand Lover but Love my Pocket.

This is the first time I've used this new oil, so I'm hoping this is the best! I have confident in this product! Most important since I'm living off Social Security, I'm on a budget. Very reasonable price for me!

really good product
