    I want to believe that something is going on in the background, but I have yet to actually feel or see any differences. It has been about a month since my oil change and introducing this into my engine. I’m giving the product 3 stars as it hasn’t had any adverse reactions, but I can’t quantify yet any positives from adding it in. I’ll do it again for the next oil change but that may be the last before I switch back to Lucas. My vehicle is a 2001 Mitsubishi Galant with 212k miles. Like I said, the engine runs relatively well and I’ve been pleased, but I’m not certain of the benefits, if any, at this point. Actually, the more I think about it, I have experienced a bit of a rougher idle and some slippage upon acceleration. I can’t say if that is a result of the oil being thinned out by this fluid, or if it has cleaned it up so much that I’m now feeling it. I have not, however, used this in my gas tank. I have been using Lucas religiously at this point for the last 2 years. I doubt there will be much advantage from a gas additive at this point, but I will may try it.

    Overall, I suppose it may have some great properties when used as a fuel additive. I can’t speak to any benefits when adding it to your oil (yet). I will use it in the next oil change and see if there are any improvements. I’ll follow-up with an update after I have done that.

    *UPDATE* 6/8/16
    So, I am in need of another oil change and I have noticed some drastic changes since I first put this in. It’s very clear to me that this product cleaned out some gunk in my engine. The results were not what I was expecting, instead of smoothing out my idle (which I think there has been some improvement there), it now burns off more oil. I am contributing that to the fact that it simply exposed the flaws in my seals. I don’t mean this from a negative, destructive way, rather it cleaned it up so much that my failing seals are now actually failing instead of being gummed up. I now have some decisions to make as to how I’m going to fix the issue (some other fluid most likely). Until then, I believe I a done using Mystery Oil, although I am impressed with it’s ability to clean out my engine. Actually quite pleased with the results, increased a star!

    Lol. This stuff is like a miracle cure for everything!! Pretty sure carpet baggers sold it for an constipation cure in the old Wild West days!!
    Just kidding, however you can free up rusty bolts, add to fuel tank as additive, clean gunk off hands or anything really! I used it in my power steering unit on my boat instead of the highly priced alternative!

    Won’t know for quite a while. Depends on how long my generator and snowmobile last compared to others.

    Now my car is a 2008 dodge charger 105k miles the engine light came on at 101k miles and my warranty expired at 100k (-_-) Go figure right? lol so i have a Evap seal leak and after paying Aamco 645+130 for a smoke test and having to return 3 times for the same problem they told me were not gonna fix it because “now the problem is in your EGR valve and not the Gasket where we fixed it” come to find out there were holes in my gas tank and the work they did was BS……so being broke i needed something to hold me over so i looked on youtube after seeing good reviews on here and i saw alot of good things.i tried it in my oil and in my gas tank didnt use much and i have to say i did notice my car idling smooth considerably better then before i also had just started using that tracker system crap on USAA.com and it monitors your milage per galon and idling and so forth and the idling went up 1 notch.Id urge you to give it a try i plan on buying another when i get a oil change and get the evap seal leak fixed

    UPDATE** Went to firestone they said they noticed my egr was new and suggested that i get a fuel cleaning (It was installed a year ago* i told them no thanks then 3 weeks later my egr valve code popped up (Too much of a coincidence) .Frustrated i turned to Marvel Mystery Oil again in the gas tank close to needing a fill up and the code went away after a few days.

    UPDATE** Once again my car tripped a Egr code P0404 9-20-15. Not remembering what the last code that tripped before i used MM i got irritated thinking id have to take it to a shop and spend a couple hundred bucks BUT I Turned to Marvel again before needing a fill up and drove the car a week and the code reset its self so im guessing again my egr got cluttered with carbon deposit and the marvel burnt it away.This stuff is really amazing (-_-)
