I've read lots of threads about this but have a couple of questions before I go ahead and use it.

I bought the 32oz bottle today at aid auto for like $6.50. I just filled up today also. Is it okay to go right ahead and put the recommended amount (forget what it is, either 4oz or 8oz per 10 gallons of gas) right into my gas tank?

I'm scheduled for another oil change 11/15 or like 92500 miles (shop recommended, so its 3 months or like 3000 miles). Should I add the marvel mystery oil to my oil now? I'm not sure how much oil I have in the truck so I can't really tell how much I should put in, or should I just put it in til it reaches the FULL line on the dipstick?

Do you have to keep adding MMO every time you fill up to keep the effects or how long is it good for? Same questions about in the oil.

 

I dumped 1/2 a quart in my oil when I changed it, and the other 1/2 in the gas tank. I forgot how full the tank was though.

You could add it now to the oil but if your gonna change it soon won't work as good. I'd just want until you change your oil. Also you don't have to follow the directions to a pertect T when putting it in your gas tank.I just estimated and went a bit over the recomended level with no problems, just don't go WAY over the limit, like twice as much ha

 

i'd wait until the oil change. I also never saw much of any difference using it in the tank on a gasser. the thing to use is BK44 or chevrons Techron additive in higher concentrations. it'll clean off the carbon buildup and help clean the injectors.

 

mmo did nothing for me when i put it in the gas tank. and i put 3/4 of a bottle in my engine about 3 weeks after an oil change. as far as the engine goes, i dont notivce any difference. but ill asdd it again nexct oil change

 

we just put a quart in with the wifes oil change last weekend. she gets around 30~31 mpg consistantly so it'll be interesting to see if she sees the same benifit Teyanna saw in her honda.

 

If I were to want to test MMO out to see if I like it or not by putting it in now, should I fill it up to the FULL mark on the dipstick?

 

yup, dont over fill it. you should notice it running smoother fairly quickly. any lifter noise should also go away.

 

i put in some STP fuel injector cleaner seemed to clean it up a bit, runs smoother might help ya out $2 bucks a bottle

 

the injector cleaner will take care of the injector nossles and carbon buildup on the valves & pistons but wont help for anything else internal on the motor. thats why it's best to put it in the oil.

 

Okay and just to confirm, for the next oil change, is it safe to put 4.5 quarts of regular oil and 1/2 a quart of marvel mystery oil? Is it safe to leave the MMO in there until the next oil change?
