Dutch, I think 120,000 miles is a typo, but at that mileage, just change the engine. Remember the gallonage of oil in a Detroit crankcase, which will hold a lot of junk without diluting the oil too much. So, 6,000 to 10,000 miles is a reasonable figure. (That's why there is a preview feature on this board, to prevent wisecracks like the first part of my answer, sorry.) George | ||

You'll get a lot of different answers from a lot of different people, but the one I liked was to: Get an oil sample and have it analized, it not only tells you if the oil needs changed, but can tell you a lot about the condition of your engine. What does your book/manual say? Also this bulletin board is archived so you can click on the "search" feature and read all the post on any subject over the last several years,(I've been reading it for about 4 years now) as it comes up on a regular basis. Usually every 3 or 4 months. The search feature has a wealth of information useable by everyone. It is probably a better source of information than "da book". Ed | ||

You would think that on DD's your adding oil all the time from it being burned/leaked that you could consider your engine in a state of constant oil change. And that you would only have to change the filter.  just kidding..... I change my oil every 3-4 months. In fact I am due for a change now and will put in 40WT for the summer. | ||

If you have a hobs (?) meter than changing oil on time is acceptable, I may be wrong but most of our coaches have sitting times of 3-4 months all the time. IMHO milage is the only good berometer for changing oil, 6-10k is accurate depending on severity of use. "Time" means little because oil never changes with time.It never "wears out" it only gets contaminated | ||

I agree I wouldn't go over 10k or 1 year in the kind of service we see. My "work" bus that is driven 75-100k per year gets changed no later than 12k. I also agree about only using 40wt Delo 100 in the 2 strokes, as it is the ONLY oil that meets the DD spec. BTW Dutch, did the shop I sent you too do a good job for you?

I store my bus in doors-the last oil change I went 2.5 years-but also had the oil tested. Those that are changing the oil every 3-4 months are just wasting their money. I used to change my 8V-92TA at 12,000 miles and got an almost unheard of 500,000 miles out of it before overhaul. I would suggest every 10,000 miles or once a year if you are not going to test the oil. Personally-I test my oil for exact time to change. Good Luck, TomC | ||

The oil chart in the book shows to use 10wt, 20wt and 30wt depending on the seasonal temp. Prior to me getting the bus the owner used Delo 15-40. I have been using Delo 30wt because it is easier to find, but will be going to 40wt as I found a NAPA that has 40wt in stock.  | ||

Hello. On the chart Austin has provided, please note the location of the hard end of the arrows, they are not pointed on both ends. The thinner stuff is not your friend if it starts to warm up. With the possible exception of those of us in the distant and far north who see the temps fall off the bottom of that thermometer....and stay there... I run the 40 wt all the time, and just about all busnuts will find it suitable. In the cold, you will be pre-warming the engine to get it started anyway, which will help the cold oil get flowing. And those of us using our coaches in the north in winter have auxiliary methods of boosting the engine to proper operating temps, so oil viscosity is not a big decision. If you are unable to make operating temps, do not have a method of pre-warming, then you have some engine lifespan issues beyond oil viscosity. And most busnuts report oil consumption moderates once on the 40 wt. happy coaching! buswarrior | ||

For those of you looking for 40 wt oil I went to the DD dealer and got their own brand of 40 wt oil Jerry | ||

On my MCI, I changed the oil every 3K miles. I had to add a gallon at 2K miles, another gallon at 3K miles, and another gallon at 3.5K miles. I figured I was $$$ ahead by changing the oil when my consumption went up so high. Mark O. Castle Rock, WA | ||

Mark, ours used to do that, too. Then, I installed a toilet paper filter and the consumption fell off. We seem to get 550 to 600 miles to the quart, even after 12,000 miles on the oil. The engine has about 60,000 miles on it since rebuild. For what it's worth. Tom Caffrey PD4106-2576 Suncatcher Ketchikan, Alaska | ||

Tom Could you elaborate as to the installation of an extra ? filter, that would result in reduced oil consumption ? Joe. | ||

Joe, there are a couple of makers of toilet paper filters, Gulf something and Franz, for example. The idea with the toilet paper filter is to filter into the less than one micron range to take out most of the soot. Some oil analysis reports show the soot concentration in percent; 6 percent is time to change the oil. The filter element lasts about 1,500 miles, the way we use it. We're finding that our soot concentration is between 1/2 and 1 percent with the toilet paper filter, so we just watch out for expendable additives and TBN. When these get low, say below 50% of new oil, I start looking at an oil change. These filters can be found on eBay, occasionally. For what it's worth.

40 wt Dello 100 can be ordered from O'riley auto parts by the case in gallons if you have one near you. And please, please only use 40wt oil (You are just going to have to trust me) | ||

I read from a fellow Busnut that he used one Gallon of Lucas oil additive and a bottle of slick 50 high mileage with every oil change, also stated leaking and blowby will normally dissapear. His article was very informative so what se ye all. Randall,RJmule | ||

Lucas is great stuff, especially for worn engines. I have seen it cut oil consumption in half. | ||

Reading all the oil talk ,it seems some folks out there still run 15 / 40 cheap oil that they get on sale . It seems that they dont relize that the delo 100 40wt is the best for them two stroke leakers . When all that cheap stuff starts to bleed outta the engine the people always call them green oil leakers . the engine usally will out last the gaskets is all |
