ARCHOIL on most recent oil change.
Just did a Rotella T6 5W-40 oil change today...even going so far as to change the HPOP oil as well. I would be adding a dose of ARCHOIL as per their directions and I wanted to make sure I got as much of the old stuff out as possible.
HPOP holds about 800 ml of oil, so I added a tablespoonful of the additive to that reservoir, then drained the sump...new filter...new oil and the full 12 oz of ARCHOIL.
I've put a dozen or so miles on it so far and to tell you the truth...I haven't noticed anything amazing or noteworthy. The engine isn't any quieter than before...starts the same as always...too early to judge mileage.
But...being an easy mark for a product with the sorts of claims it makes...I'll be watching closely. I'm hoping that there is SOME truth!
I ordered a 7.3 PSD Package that came with the friction modifier and fuel additive.
Anybody else use the stuff? What is your opinion on it? Worth it?
BTW...mine is a 97 with just over 112,000 miles...so maybe I don't have enough wear and tear for it to be noticeable!
