8000 miles or once a year, whichever comes first.

That's my opinion. That's about how many miles we put on a year, so it typically works out to once a year. I'm adding a gallon about every 1500-2000 miles.

On a 2 stroke I agree wih Craig, 8,000 miles or 1 once a yr which ever comes first! BK  Grin

H3 you should be able to extend that to 15,000 on yer 60 series but then again doing it the way you are assures you'll always have good oil! BK  Grin

Thanks Guys,
   I usually have all the fluids and the filters changed in the fall before the trip south, 6000  miles. After thinking about it I think the problem in my case is not the miles driven but the 6 or 8 months it sits.
PLUS, I take it to Southern Oregon Diesel and while they change the fluids they inspect EVERYTHING under the bus so when I leave I know the condition of everything. That makes me much happier when driving down the road a stranger in a strange land.
While thinking about how much money the trip was going to cost I forgot a couple of important points. Thanks for stirring up the sleeping brain cells.

Depending on where you live.  I live in L.A, so no really big temp differences and I keep the bus indoors.  My last change, 6 months before I changed it I had the oil analyzed and it came back OK-and that's after 2 1/2 years and 5,000 miles.  The bottom line-if you really want to know if you should change the oil, have it analyzed.  That's the only really accurate way of knowing for sure.  So ultimately, I had gone 3 years before I changed the engine oil (not saying it was correct or you should do it, just that it turned out OK). 

Jerry- what you are doing taking it to SoOr Diesel for a yearly checkup before the long trip is the smartest thing anyone could do. Especially if you don't know what to look for and are not a mechanic yourself.  Good Luck, TomC

Jerry,

You're right on track. I didn't mention it earlier, but I don't change my own oil. I do most of my own mechanical work, but the oil is not one I tackle. There are a couple reasons for this. The first is I don't have the capacity or desire to deal with 8 gallons of used oil at one time. I don't have a shop or pit, so I'd have to do it on the driveway on blocks. Trying to herd 8 gallons of used motoroil while on my back or belly is not my idea of fun. The main reason, though, is exactly as you said. Once a year, I get to have professionals put my bus up on the racks, and go over the undercarriage with a keen eye. They check the work I've done to make sure I haven't missed anything or screwed up anything. Costs a bit more than doing an oil analysis for several years, but to me, it's money well spent.

I'll second Craig's approach as I do the same thing.  Well worth the dollars to have C&J Bus's crew look over the bus while doing repair work.  Having them do the maintenance also goes a long way towards earning a little "free" advice when needed as the repair shop usually doesn't mind giving out a little knowledge now and then when they know you are a good repeat customer.

Well being the tight wad I am! I change our own oil every 1-3 months (8,000mi) in our coaches! It would cost too much to drive up and let JD and his crew of professionals do it for me! Besides last time we had a bus serviced out on the road (during Hurricane Katrina Relief) it cost me  fortune and they didn't even have the right oil (which I'd asked for & been told ya no problem!). Took 6 hrs and $300.00 and 6 gallons of oil I had on board! That won't happen again! BK  Grin

I too have the dealer do it, 40 qts of oil is just too much to deal with.  I don't have a 10 gal bucket anywhere.  They also lube and check everything.  Each time during the inspection, they have found an additional repair that would have left me on the side of the road.  The dealer has all the parts right there, so they just fix it, and I still get to keep my bussin experience fun.  They lube the kingpins too, which requires it to be on a lift to get the grease in where it needs to go.  Can't do that on the ground.

Lube service from Prevost is not much different in cost than on my car. Under $300.  Money very well spent in my opinon.  Do all the filters too.

And as Brian says, I get to pick their brains on Everything else about the coach, from maintenance, to upgrades, anything coach related.  Well worth the relationship.

I have always gone 10K between changes. Thinking about taking to 12K Had oil analyzed in several buses and always came back sutiable for additional running. My current bus uses less than any I've ever owned, a gal about every 2,000-2,500 miles. Most of the leakin DD ( or the ones I've owned ) usually get a gal about every 1,000 miles or so like a constant oil change a gal at a time. Oil today is much better grade.. I have been involved with 2 new coaches plus 10 of my own. I run about 30-40K a year. That's about 3 times a year. Just my take. What ever makes you comfortable.

Should I expect any measurable oil consumption in a Series 60?  It seems normal to use oil in a 2 stroke.  My oil level seemed to still be good after my 1600 mile trip home.  I had the oil changed before my trip.

I will probably just have C&J change the oil like Brian and Craig.  I can go 15,000 miles according to Detroit, but I will do once a year which will probably be half that.

Brian your oil consumpsion will depend on the condition of yer engine, the use of it, & the amount of miles on the oil (the more mile the thinner it is)! I'd say on yer trip with the mountians, and distance of "straight thru driving" that you should use less than or right at a gallon each way! If you don't it'll show yer engines in pretty good shape for the age/mileage. BK  Grin

In general, with the older style 2 strokers, 1,000- 1,500 miles per gallon burned is normal.  On newer designe, 2,000-3,000 miles is normal, and they should burn oil-it's the nature of the beast with the piston and rings running over the intake ports every stroke.  If you don't burn oil-watch out-maybe to dry and could cause cylinder scoring.  On any 4 stroke, a tight engine should at most be down one gallon at time of change with no adding in between changes.  When any engine gets below 1 gallon per 1,000 miles, it is time for overhaul.  Good Luck, TomC

Is anyone just changing there oil based on the oil analysis results?

It would seem to be the most accurate way!  Huh

Or is "change it once a year" regardless of miles,  the makes me feel good route and its safe.

My plan was once a year (I only run about 4000 miles) and get an analysis....but I may just send in the sample first and then decide.

OK , oil experts chime in.....especially you fleet guys.....

 Just got home from GAT in Dallas..the biggest seller this year was bypass oil filters ,pm services and automatic power systems...(gen. hyd. pump and ac compressor units for no idle time)  all the major engine manufactures but one showed up with a factory installed bypass filter of their own..current pm thinking is that the major wear on a engine is fuel soot...If your oil turns black in under 1000 miles of driving then you have a soot problem...Look into subscribing to one of the current pm companies they are every where now and for low usage users average about $75. a year....If a anayliss company does not want to know what motor trans and driving style and a base line oil sample then you are just wasteing your money....whether you change oil or not is your decision based on real facts..... I haven't changed oil in any vehicle I have owned since the 80's..unless the oil anayliss showed it needed done..to each his own...gg04

Hello there gg04,

Thanks for your input to the thread - and welcome aboard!  Good to have you here.

I hadn't heard of the Preventive Maintenance company.  What is the name of one you have used or heard of in Dallas?

Thanks - and Best Regards, Phil

gg04- Having black oil has nothing to do with engine condition or filtering.  When I was trucking, I always got my oil analyzed (Speedco is a good one-have it done while changing the oil) and ultimately decided on 12,000mi for the oil change interval.  While I could have gone closer to 15,000mi, it was just easier to do the oil change at intervals of 12's on the odometer, then I didn't have to remember mileages.  My point- they would change the oil, run the engine to check for leaks, then I would leave. I always rechecked the oil about 200 miles later, and by then it was black.  Heck, on my Mercedes-Benz turbodiesel, I change it every 3,000mi and it turns black immediately-and it has 262,000mi on it.  Black oil doesn't mean anything-it just means the oil is doing its' job of cleaning the engine.  Always- Oil analysis is the ONLY real determining factor.  Good Luck, TomC

In my 8-92 I change every 15,000 km and sample every 7500 km.  The only time I ever had a sample come back telling me that I needed to change was after we changed the oil pan - we must have got some dirt in while changing the pan.  I have a good friend who used to run 8-92s in OTR trucks on furniture hauls.  He tells me that they never changed at less than 20,000 miles.  Personally I think sitting idle is harder on most of our engines than the little bit of time they spend running & I intend to stick to the 15,000 km interval.

Da book always sets Oil/Filter changes at milage intervals 'except on marine and industrial applications' - Oil has spent millions of years under the earth without degrading - time will not kill your lubricant - dirt/contaminents (fuel too from idling) will - with the high price and diminishing stock piles of crude - oil analysis may be the best thing going - no sense in wasting good oil - FWIW

One way to deal with changing the oil yourself, is to install a drain valve instead of a drain plug. This way you can catch smaller amounts of oil at a time and not try to catch 8 gallons in one shot.

If you do change your own oil, one of these 58-qt. pans should make it easy to catch, store, then recycle it. Presently, I use a big tile saw basin I got at Home Depot, then pour it off into empty gallon jugs... but that Blitz pan looks pretty sweet.

Black oil has everything to do with oil condition...for years we ignored fuel soot as just an unavoidiable by product of running our engines....times change...Black oil means the additives are working trapping the soot and keeping it in suspension...the more it circulates the more wear it causes on your engine.. . Bypass oil filters are designed to remove all contaminents...even the major eingine manufactures offer them now...modern labs have made it possible to check and contain wear...Just run a web search on p m labs and you can find one near you ...just because we have lived with it for years does not make it right...gg04
