Hey all,

Just curious to see if anyone recommends or has used marvels mystery oil in their FWB and what you think of it?

Best,

My uncle who has been a Cadillac fan since the late 60s swears up and down by this stuff. It's good for the gas, and for the oil too. I like to dump a bottle in some time before I change the oil. It helps get some of sludge out.

I add a bit of MMO to the gas when I fill up my '69. Helps compensate for all the ethanol and prevents vapor lock.

I used MMO all the time. Keeps my fuel and oil clean. I highly recommend this stuff.

Once in a blue moon I will use it, after a thousand or so miles the oil looks pretty nasty, not sure from cleaning or from the MMO sludging, being I am using synthetic it isn't.

1-2K before oil change probably isn't a bad idea....

I use LucasOil stabilizer with every oil change, and I like it. The engine sounds smoother on cold starts, and it really slows the leaky base pan I have.

So would you guys recommend dumping one full bottle in the gas tank every some thousand miles?..and another full bottle in the oil crankcase before an oil change?
