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 ### ⭐⭐⭐⭐⭐ Marvel Mystery Oil is Marvellous! *by D***. on November 10, 2025* This is great stuff. Use in gas or oil for extra lubrication. Stop engine smoking ### ⭐⭐⭐⭐⭐ Lubricates makes things last *by K***E on May 1, 2026* Keeps my injectors lubricated and my fuel pump running strong. I use this in my last car and had factory injectors and pump at 275,000 mi ### ⭐⭐⭐⭐⭐ A fine air tool oil and more *by D***N on April 14, 2020* I've been using Marvel Mystery Oil for my air tools since the early 1970's when an elderly mentor told me to use it when I was a young man just out of the service on my first civilian job. It works fine and my air tools have always lived a long and useful life with out gunking up or showing much wear. It has never failed me. I also use it for a general light lube oil and when mixed with a little lacquer thinner it frees rusty bolts about as good as anything else I've tried. My elderly mentor had been a mechanic his whole life so the history of using this oil these ways has been well proven over time. ## 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.hr/products/11868989-marvel-mystery-oil-cd-2-mm12r-16-oz-red](https://www.desertcart.hr/products/11868989-marvel-mystery-oil-cd-2-mm12r-16-oz-red) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-05*
