## Questions & Answers

**Q: Do you think this will oil a sewing machine?**
A: I am sure that it will but you can also purchase a smaller container,less expensive oil.Just about any type of oil will do.If it is a difficult spot to access you can get a can of spray oil that comes with a small about 1/8th inch diameter 6" tube that fits into the nozzle and can oil a spot that is hard to reach. 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.
