Got good results for motor magic engine flush.

Gunk motor flush, first 2 ingredients... petroleum distillate (kerosene) and more kerosene.
It's just an overpriced bottle of kerosene lol.

Could just use good oil and change it on time. that works too...

Yup. Every 3k for me and never had a problem.

I understood your point and believe it's true, but was asking if a motors maintenance is questionable at best(even though it seems to be in decent working condition) couldn't it be a good idea?

I wouldn't flush if it runs good and is quiet.

Absolutely. Anytime I buy a used car the first thing I do is run some kerosene through it and change the oil (sometimes more than once) because you never know how the previous owner maintained it. I treat any used car I buy as if the previous owner was a complete and total moron, which in most cases is true. Flush all the fluids, new filters, basic tune up etc no matter what...

I always just used pure kerosene though. Never really tried any of the off the shelf flushes because most of them are just kerosene anyway. I've heard of using ATF too because it's super high in detergents but again, only ever used pure simple kerosene.

Same thing I do when I buy a used vehicle that has engine noise to flip. But it was always diesel. I think the benzene combined with the diesel and kerosene is the trick in this stuff.

I dunno if I'd go mixing your own concoctions. Better off just buying the off the shelf stuff and sticking to the directions. When I use kerosene I use about half to a full quart depending on the size of the engine. Run the engine at idle for 10 mins or so and drain it. If it's really gross I'll fill it back up with cheapo oil, more kerosene and repeat. You never wanna drive with any kind of engine flush in the oil. Only do it at idle and then drain it immediately.

Nope. Run the bottle through it and that's it. I've known some folks that liked mixing their own and always seemed to burn one or two engines up.

If your worried about 4 bux a bottle at Walmart vs potentially saving several hundred dollars on a lifter fix then you have bigger issues. Lol.
