Very much so. I've done in on my 2002 Cavalier, which has 122K miles on it. The oil change with the MM made a big difference in mileage and performance.

 

yes it is. I'd go with a full quart for the next 3k miles then switch over to synth. it'll clean up the internals nicely.

Gary, can you post your pic of the inside of your motor before you pulled it for the rebuild?

 

Ask, and ye shall receive!

Thanks Gary! I tried to find a good pic of mine but all of them are too far away and the lighting sucks so it's not a good example.

 

Is there only one MMO, or is there one for oil treatment and one for the gas treatment? I have a hard time buying anything to put in my engine that is called "mystery oil", but I may try it. First, I am going to try the Mopar Combustion Chamber Cleaner.

I have used the BK44 in the past and highly recommend it. Never noticed any difference using it in the Ram, but it made a noticable difference in a Camaro I had back in college. Ran smoother and had noticably more power.

 

I was skeptical too but figured what the hell, "i'm one with my motor" so if it messes it up, I know how to fix it. turns out it was one of the best things I could have done to it. lifter noise... gone... ran smoother pretty quick. and this was with only about 12 oz in the crank. thats why i recommended it to T (daughter) and she ended up doing a full quart in a 4 quart motor (honda) and got significant improvement in mileage 23~25 to 29~31, consistantly.

 

I perfer the engine Restore (it comes in three different sizes 4cyl, 6cyl, 8cyl) at each oil change for cars over 75,000miles

 

We call that stuff "Liquid Chrome". I've added that to an engine that smoked really bad and it cut the smoking by 90%. I think using Engine Restore every oil change, on an engine with over 75K miles, is a bit extreme. I would use MMO for every third or fourth oil change anyway.

Overall, if you maintain an engine properly, it will last for many thousands of trouble-free miles. My Cavalier is proof of that.

 

my 2000 360 motor had 180~185k on it when I sold it and it was rock solid... ran mobil 1 15w50 for the 60k miles I owned it and the only additive I used was the MMO for 1 oil change. the last time I did a comp check on it it had 155k on the clock and all the cylinders were at 150psi and above.

with todays oils, I dont think you need anything other than proper maintanance. I think the MMO is good for cleaning the motor and should be used 1~2x year. it would be interesting however to see what T's motor looks like under the valve cover...

 

can you buy MMO in canada? cause I've looked everywhere for it and I cant find it. my truck just failed the e-test and maybe that stuff will help me pass.
