Oil is ,of course, a lubricant any oil will do.The lighter an oil is the more often yo may have to oil that particular part.Many years ago when I was in High School I made a salad bowl on the Wood Lathe.We had run out stain and I anted to keep the natural wood-look.he next day the shop Teacher brougt in Cooking Oil. That was 52 years ago nd I still have that Sala Bowl and every few years I apply more oil.Now I use Vegatable Oil. I hope this may help You. **Q: I think i have a clogged oil passage will this product break it up and allow the gunk to pass through?** A: I found this to be pretty amazing stuff . I had a VW bug (1600cc engine) stored in a back shed for 25 years that I changed the oil and added a pint of Marvel Mystery oil in the change (VW's take 2and1/2 quarts in the change), put some gas down the carb , turned the engine over two or three times and the darn thing fired right up. I don't know if it was luck, German engineering or MMV but the engine kept smoothing out the longer it ran and I'm sure the MMV had something to do with that . To now answer your question , I really can't tell you , but from my experience this stuff is well worth a try and it definitely won't hurt. The price is right. Good luck. **Q: I have a 2005 Chevy diesel that smokes sometimes, especially after idling. I was told this might help. anyone tried it for that? how'd it work?** A: I would tend to say not likely. It is a good high quality high detergent oil that is used to help clean deposits out of the engine, but based on the limited info given it sounds like you may have worn out engine parts. It is a great oil for many uses, but I suspect you have deeper problems. **Q: Can i use mmo for my car tucson 2012 of diesel crdi engine?** A: There are tests published that this product isn't a great thing to add to diesel fuel. The packaging says it's fine, but there are independent tests showing it lowers lubricity of fuel which is hard on top end and injectors. Check out archoil 6200 or revx instead for this use. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Price for a 2 pack and it WORKS! *by on Reviewed in the United States April 26, 2019* I've always wondered about Marvel Mystery Oil as I've seen reviews along with various YouTube videos about the benefits of this product. So I decided to give it a try. Make sure you follow the instructions on the label for the application your using it for! It doesn't take a lot, whether adding to your oil or your gasFirst I put some in my gas tank at the recommended amount (4 oz per 10 gallons). Most people do this 2 to 3 times to get the full benefits of the product. So a 16 oz bottle of Marvel Mystery Oil would treat 40 gallons of gas. It has improved the performance of my 2011 KIA Sorento 4 cylinder after using on 40 gallons and I'm going to change the spark plugs now. On my significant others 2002 Toyota SR5 4runner, we've had issues with 3 of the idiot lights always staying on, which I've read could be the O2 sensors. On the 3rd application (I used a bottle, 4 oz per 10 gallons, 4 times in a row) those lights went off and have stayed off for 3 months now! Did it clean out the O2 sensors? I'm going to say yes because they have been on for a full year!Then I added some to my KIA's 4 cylinder oil. You can add or replace 20% of your oil so if you use 5 quarts of oil, you could replace 1 quart of oil with Marvel Mystery Oil. I had changed my oil around 3,000 miles ago with full synthetic Castrol Edge along with using a high dollar synthetic oil filter. This synthetic oil has been so "clean and clear" that it was difficult to read the level on the dipstick. But it was like a 1/2 quart low. So I added 10 oz directly to the motor. 200 miles later, the oil went from almost being clear to black!! So it definitely was cleaning something. I drove it 300 more miles and then changed the oil and filter. I had read that you should add this product like 500 miles before your scheduled oil change and now I see why! My KIA is purring like a kitten and I'm getting 3 more miles per gallon on the highway (78 on the interstate).Finally, I had added some (4 oz) to a 1 gallon gas container for my lawn mower and the some to the 1 gallon mixture of gas/oil for my old Toro snowblower. The snowblower had been running rough and occasionally dying on me. By the 2nd time I refilled the Toro's gas tank, that 25 year old Toro was once again running like it did when I got it new! I'm serious here! Then this Spring (right now), it naturally was added to the lawn mower. I just got done mowing the yard for the 2nd time this year and it uses 1 tank of gas to get the entire yard done. When I went to start it up, it started on the first pull as usual. But a HUGE gray smoke cloud came out of the exhaust! And it's never done that before. But it's purring like a kitten too!I'm no mechanic but am rather handy. Just installed a new capacitor on the outside air conditioner as it wasn't cooling. And it solved the issue.Marvel Mystery Oil says it improves compression, power, & MPG, along with lubricating upper cylinder for smoother idling along with keeping engines clean from sludge. Based off my results or experiences. I would have to agree 100%. I'll keep adding a little to the gas now & then. But if I add to the oil, I will only due that like 200 miles before the next oil change. I recommend trying!!! ### ⭐⭐⭐⭐⭐ Excellent product at a good value *by on Reviewed in the United States April 26, 2024* I have been using Mystery oil for over 30+ years with every oil change to keep the engine well lubed and the internals clean from sludge. I purchased and older truck that had low oil pressure, the engine is known for bad pressure sensors that get gummed up. I did an oil change and added 16oz of mystery oil then started driving the truck. The oil pressure gauge was running 0 to 10 psi before the oil change and after it started to climb up 20 to 30 each time I drove it got better. After a few hundred miles the gauge was reading 40 to 60 psi where it should be. I have not had an problem with low oil pressure since it keeps the internals clean and well lubed. I am very happy with the product and its multi uses I would recommend it. ### ⭐⭐⭐⭐⭐ Great product and multiple uses. *by on Reviewed in the United States February 28, 2026* Been using this product for years now. Great especially as a fuel additive for cleaning carbon deposits from cylinder walls. ## Frequently Bought Together - Marvel Mystery Oil CD 2 MM12R - 16 oz., RED - Gumout 800002231 Carb and Choke Cleaner Jet Spray - 14 oz. - Gumout 5072866 Starting Fluid - 11 oz. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/11868989-marvel-mystery-oil-cd-2-mm12r-16-oz-red](https://www.desertcart.gr/products/11868989-marvel-mystery-oil-cd-2-mm12r-16-oz-red) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-02*
