Engine Oil stabilizer???

I'm not an oil expert but I sure wouldn't run the standard stabilizer when the bottle calls for the synthetic, so why bother testing the standard? And what about Prolong? have you had good luck with that? If there is an additive worthwhile I would spend the money on it for my truck.

well, like i said in an earlier post, with the synthetic lucas, my truck does seem to run a little smoother especially on long oil changes. i intend to send in an oil sample when i drain my oil ( probably next week ) and i'll post the results. i intend to use auto-rx on my next oil change and go through the cleaning process it recommends and possibly continue to use if afterwards for the friction modifiers it offers.

It has been recommended to add Prolong when you change the oil in the top end, that is what I did and it seems to work really good. My motor runs much smoother now and doesn't make nearly as much rattling noise.

Worst mistake I ever made was putting in the Lucas non-synthetic stabilizer, (at 60 it bucked liked the wheels were coming off) since it didnt help much on the first oil change I tried it again (what a dummy). Then on the next one I tried some of the synthetic additive, it ran just as bad as before.

The reason I tried it in the first place was; after I used some of their Diesel fuel additive it seemed to make it run much better, hey, if a little is good allot must be better, right?

Finally after 3 oil changes with no additives, then recently changing the oil in the top end it is finally starting to run like it use to.

Just a FYI for you in case you do not know, the "Top End" oil is the same oil as is in the oil pan. It circulates together.

That is the theory.

[bugman]

Not theory but fact. The oil goes from the low pressure oil pump to the high pressure oil pump then it is delivered to the injectors through the high pressure oil lines and cylinder heads. The injector uses the oil pressure to inject the fuel into the cylinder and then out of the injector to the valve train area. From there is flows back down to the oil pan. If is was a closed system when you pulled your valve covers off and ran the engine you would not see any oil coming from the injector but have a return line connected to it to recycle it to the hpop.

Your sir are correct, and you know I have found over the years that every time a designing engineer has designed something for use they always have taken everything into consideration and the end results are always as they expected.
