Gary Allan I agree with you. Unless an engine in a car or truck is a 'sludge monster,' just using good quality motor oils with reasonable OCIs should work perfectly good. Nobody has to buy Auto-RX or any other product to clean the insides of an engine and there are products out there that could cause harm to an engine rather than good. I have always felt that 99% of all the oil supplements on a shelf in an auto parts store are useless.
I feel that Auto-RX is probably an exception to that general rule. I think Auto-RX works but I can't prove it.
Some of the few other products I believe in are Lubegard products because I have had good results using some Lubegard products. In fact some car manufacturers actually approved the use of certain Lubegard products.
I think a person is usually better off not using a lot of supplements for the engine or anywhere else. But if somebody has a seal leak that is not caused by physical damage to a seal or a high mileage dirty engine (or maybe is buying a used car with a dirty engine) I don't think it hurts to give Auto-RX a try. It is a cheap experiment.
