Frank, thanks for your reply, I also put your product in my dads riding mower that is 13 years old, it was using oil, i had to add some each time, i put in 2 ounces and it stopped leaking oil, i also put some in our push mower and it virtually stopped smoking, i added a maintenance dose to my 04 marauder and saw a little better gas mileage as well as some more power, in my 83 chevy my mileage went up by 2 miles when i changed the oil at 1500 miles it was a little dirty, the car definetly has some more power, your product does prove that even if you use synthetic oil there will still be some deposits, thanks for making such a great product, i will be ordering 6 more bottles and using it as a maintenance dose in all of are engines, i dont listen to the naysayers at bitog because your product works, when i changed the oil filter at 1500 miles it felt heavy even though i drained the oil out of it, i guess all the junk is in the filter, i am saving the filter to weigh it and eventualy cut it open.
When using Auto-Rx in a lawnmower engine with no oil filter make sure you change the oil after 8 to 10 hours of running time on the engine. I have a riding mower and was using 3 to 4 oz of oil ever 3 hours of engine running time after Auto-Rx cleaning it stopped using oil. After cleaning I started using 1oz of Auto-Rx in 1 quart of oil and it has worked great.
