No, I wasn't having any problems at all when I started on MMO. I have been using it for about a year now. My truck is a bit on the slow side. It is heavy for a mid-size pickup: it weighs over 4,000 pounds and it only has a 6 cylinder 175 hp engine. It is underpowered for its size and weight, but my old-school cast iron engine is very reliable and durable.
After I read about MMO here on BITOG and on the MMO website, I started using it to try to increase my engine's power and performance. And even if it didn't help my MPG or performance on the butt-dyno, I would still use MMO for its UCL properties alone. I want to keep my old truck running the best it can and keep driving it as long as I can. Until the wheels fall off, some would say. The MPG increase I get is a very welcome side effect of the UCL properties of MMO.
MMO can help keep an engine in good shape, but in my case it wasn't instant gratification like you get with the strong PEA-based fuel system cleaners and fuel injector cleaners. MMO is a good solvent and a mild cleaner. I had to use MMO for several tanks of gas before I noticed any improvement in how my truck ran. But when I added a pint of MMO to my oil, my engine immediately ran smoother and quieter and it seemed to have a little more power. That is because MMO will thin your oil a bit. In cool weather it also made my truck start right up the instant I turned the key.
MMO is a good product and it has been around a long time. If you need a good UCL and an additive that can help your engine run better and last longer and keep the fuel system cleaned and lubricated, MMO is about the best additive you can use. I researched and read online for a very long time before I tried it, and I never found even one post from someone saying MMO damaged their engine. There were a few who said it did nothing for them. I suspect they didn't use it long enough. Some were like me and had to use it a while and others noticed a difference as soon as they pulled away from the gas pump after adding that first dose of MMO. The key is consistency, you need to add it at every fuel fill to get the most and best benefit from it and you may have to play around and adjust the dose amount until you find what works best. Some guys use more, some use less.
Walmart is the cheapest place to buy MMO and Regane too. I stock up on both on my occasional trip to Walmart. With Regane you want to get the one that says Gumout Regane Fuel System Cleaner, not the Injector Cleaner. You can run a tank with Regane and then start on your MMO treatments. Whether you keep using MMO or not, Regane is a very good cleaner and it only costs $4.50 at Walmart. As little as MMO costs, $3.77 for a quart at Walmart, it's definitely worth trying.
