Re: Driving 17 hours to pick up bus...what to bring?

Check the air filter!!
I caught a bus on fire driving a new purchase over the cascades in OR. Its muffler was against the firewall in back, right where a bunk had been built. I didn't check, and the filter was horribly plugged. The air restriction caused the exhaust temp to go thru the roof while climbing a very long steep grade and caught the bunk on fire. Thankfully it was spring and there was lots of snow on the ground!

It wasn't my cousin's brother, it was my grandmother, thank you very much. There is a study that included all the fancy additives including the 2 stroke oil and it outperformed many of them.

When I bought my e350 in NY, I tried 3 different additives and they all worked like crap. After I put in the 2 stroke oil, all it took was about 5 minutes on the freeway for the engine to go from scream to purr. What do you think 2 stroke oil is? It provides lubricant to an engine with no crank case oil. If you don't want to use it, that's fine.

Re: Driving 17 hours to pick up bus...what to bring?

I like your logic...how much 2 stroke oil for my 6.7L engine would be good?

Thanks for all the advice guys, I fly out Friday!

6.7 as in the new Cummins engine? NONE! After 2007 model year, you can only use ultra low sulphur diesel or the EPA fascist swat team will fly in with black helicopters and arrest you. All the new engines are designed for ULSD. I think the oil will screw up your diesel particulate filter or whatever the hell they call it.

For those that don't know or remember, when they went from regular diesel to low sulphur diesel, sulphur content went down to 500 ppm. When they mandated ULSD, the sulphur content went to 15ppm. Sulphur is what lubed your injection pump and injectors. I don't know if anyone remembers all the problems after the first change. That probably killed most engines that were borderline. My theory is that's why we didn't hear the same thing the second time around because so many of the old diesels were already dead.

Maybe some of the truck drivers remember a device that would automatically inject some of your crankcase oil into your diesel tank for lubrication. That was before they screwed with the diesel formula.

Boy, I sure used the word remember a bunch of times, huh? Oh we'll.

Re: Driving 17 hours to pick up bus...what to bring?

Just to show you that I don't know what the hell I'm talking about or maybe just talking out of my ass, I present you with the study I mentioned before. Walmart 2 stroke oil came in at a respectable 7th place not too far behind 3rd-6th place. That was out of 19 places. Power Service came in at 10th place.

If you think that today's diesel is good enough, it's not. Additives are not just for vehicles that are on their last leg. Go ask a fuel injection shop what it costs to rebuild an injection pump on your bus. I'll bet they don't give you a figure less than $1000 if they give you any figure at all. If could go as high as $3000. Do what you want with your bus, I know what I'm doing with mine.

Oh yeah, I almost forgot, Howes came in 11th place.

Re: Driving 17 hours to pick up bus...what to bring?

I noticed the ratio was only 200/1. I wonder what the effects of a higher ratio would be.

An engine builder on a motocross site I used to go to recommended the cheap walmart 2 stroke oil, but in that sport, $120 will buy everything you need for a top end if the cylinder is good. What I saved in 4 gallons of oil paid for it. I used chain saw bar oil for my air filters, because it appears to be the same stuff as filter oil, sticky, stringy. The exterior of the filter could get caked without visible dirt on the inside with either product. The price difference? $8 a quart vs $8 a gallon. For those that didn't know, dirt bikes take foam filters you must clean and re-oil.

I have always questioned how much science really goes into additives/oils in general, secondly how much effort goes into creating a special product, not just a blend of what would be available to the consumer.

Re: Driving 17 hours to pick up bus...what to bring?

I started with 32 oz in a 40 gallon tank. Every fillup, I added 16 oz. That was for the 7.3. All of this was before I read that study. I just couldn't stand the engine screaming at 55 mph and everything my friend told me I should use wasn't helping. After I put in the Walmart oil and I told him about my results, he said it was in the study also. WTF? Why didn't he tell me before? I can't prove it but my mileage numbers went up over 1 mpg according to my calcs. It wasn't a scientific test but I was pretty consistent with refueling methods.

So to answer you question about how much, I don't think more will hurt but will it actually help? I think the by the gallon price works out to about $0.10 per oz. so adding the 16oz every fillup was costing an extra dollar sixty. The concentrations were increasing because I was taking on 10-15 gallons.

Now with my DT466, I couldn't tell the difference because the Walmart was about 1-2 miles from the school yard. I bought and used the oil from the very start of my trip. My engine is the very last year of the P-pump mechanical injection DT466. I bought that bus for that reason. It's a 1997 and they had started switching over to the DT466e in 94-95 I think but some mechanicals were still available until 1997. An injector for my bus can be had for about $50-70 per injector. The electronics are about $250-300 plus per injector. The sled pulling guys are getting over 1000hp out of these engines.

Thanks for the tip about the chain oil. Can it be used for a K & N filter also?
