Thanks for all your posts about oil & filter preferences.
What about oil additives? Anyone use them? I was reading the Lucas bottle. Sounds like miracle fluid!! So, I figured ya'll could let me in on which ones are best or if it's all hype!! I gotta make this thing part of the family for another 200k at least!!
Oil companies spend mega bucks formulating their oils so anything you add would possibly do more harm than good . I won't even use another brand to add to my motor if it gets a quart low much less some snake oil . Save your money. Good luck on your quest for 200K.
Southerndually..
Just courious... If you've heard horror stories about additives, and straight oil is doing a good job for you to get your truck to high mileage, why would you want to start using an additive ?
I only use snake oil to lube my muffler belt.. I'll do that when I adjust the linkage at the turbo housing while checking the clearance on the Diesel Oscillation Pressure Escape Yoke (D.O.P.E.Y.) Which is located next to the emergency brake fluid jettison valve.
I personally use Lucas oil treatment. I am friends with a head Mechanic for a mojor trucking company in my area and they run lucas in ever truck in their fleet. They recomended it so I tried it and now I'm hooked on the stuff.
I too worked at a trucking company. We had a fleet of over three hundred tractors and we did not add anything to any of them when we peformed the maintenance.
So you're "hooked" on it?
What are you hooked on?
Better performance? fuel mileage?

Talk about learning. This has got to be one of the best threads on oil that I've seen to date. I had just purchased some of the oil additive and needless to say, goes to the chain saw. It will not be going in the PSD. This Bobtheoilguy seems like a real knowledgeable individiual. It would be nice to be able to really sit down and talk with him a while about things like Trannys, rear ends, and of course 7.3's.
I started putting in Lucas this year and to tell you the truth I noticed the engine not running smooth going up to Lexington, KY.
Diesel Daddy great question. Heat Stroked thanks for the site. No more Lucas for Old Gray.
Well for the full story, I do see slightly better mileage. Actually the thing that sold me on it more than anything doesn't have to do with diesels. My best friend and I were deer hunting last year in northern PA. It was in the low teens over night and my buddies truck with a 351w in it has over 300k on it. when we started it one morning it was carrying "0" oil pressure. The oil was too think to pump from the cold. after 5 minutes of running it started to get tight from heat. If any of you have heard an engine run dry let me tell you it was not sounding pleasant. We got a gallon of lucas at a nearby store, warmed it up a bit in hot water put that in and topped it off with oil and fired it up. It smoothed right out and purred like a kitten. That was over 10k ago and it's still running fine. I'm sold on the stuff!!
