    The shipping delay was not the fault of the seller but USPS. The package was wrapped to handle a 20 foot fall. The item was delivered in perfect condition and looks great. Great price,great quality. thank you.

    Keeps an older engine young

    I started using this product in the gas tank of my 1993 Ranger p/u at around 200,000 miles, maybe less. She now has 355,000 miles on a basically original engine and still runs like a new one most days. 4 oz of MM Oil to 10 gls gas (mine runs on mid-grade, regardless) keeps the upper cylinder, injectors, etc clean & lubricated. I could tell the difference on the second use. That was a long time ago. The bottle is graduated, so 4 oz is easy to pour. I end up buying gas 10 gals at a time, which is limiting in a way, but it's not an inconvenience. I'll keep using MM Oil this way as long as the engine holds out.

    What else can be said, Sold since 1930's & STILL keeping up wY2K Technologies? YES, you need this.

    Basically, I'm left with only a few mysteries to solve on this oil/gas additive. Noticed online there are a few poo-poohers of MMO, but the fact so many take confidence in it and seem to experience lower fuel consumption with smoother running/ longer-lasting engines ought to be 'nuff said. I've used MMO off/on since the late 1980's and find it "always does the trick" when my engine/fuel system needs a little "fine tuning". Engines always run smoother and things feel better, though I never personally feel this is needed in every tankful- maybe once a month. One thought several older fellas in my circle are discussing though, maybe you consider too, is that everyone agrees this new Ethanol-laced gasoline has dramatically negative effects on typical combustible engines and especially the ...

    I use it to put in gas as upper cylinder lube. I have used this for over thirty five years. More important today with the ethanol mixed into the gas.
