After reading lots of positive MMO comments, I picked up a quart a couple of days ago.
Yesterday I put 4oz in my 93 S10 Blazer's gas tank (half full) and 8 oz in the oil, which has about 2000 miles on it's last change, still golden/amber on the dipstick.
I got this Blazer a couple of months ago with 91k original miles, pretty good condition for the year. The main issues was a slight miss/surge when going at slower steady speeds, and after it has sit for several hours (typically overnight), it will blow a puff of smoke after starting. Just that one pretty good puff of smoke the instant it starts and not a spec afterwards or during the day after it's started again while warm. I have read that's pretty normal on this year of 4.3 Vortec engine due to the valve stem seals.
Put the MMO in the oil day before yesterday and ran it for about 10 miles. Started it up yesterday after noon after sitting a good 12 hours or more and not a hint of smoke on start up. It ALWAYS puffed smoke 100% of the time everytime on start up with as little as 4 hours of sitting, but a bigger puff after 6-8 hours or more. Yesterday was a good 12 hours and it was 100% smoke free on start up.
I let it sit about 6 hours or so and started it up again later yesterday evening.... again not a hint of smoke on startup.
About the MMO in the gas, it could be my excitement over the smoke being gone and just wanting it to run better, but I think it definitely has a more power on take off and smoother idling. It hasn't eliminated the miss/surge (can't exactly tell what it as it's so slight) completely, and maybe it didn't affect that at all.
I know 100% that it DID improve acceleration in our 03 T&C with 124k that's been a little neglected on maintenance. On the hwy earlier this evening it had more pep on passing and accelerating. It wasn't a night and day difference but guaranteed it was an improvement.
So I'm gonna buy this stuff in gallons from now on.
If you're reading this and don't believe in MMO then fine, I can appreciate that. I know it's not a miracle oil and can't fix everything. But for my two cars it made me a regular user now.
