When do you intend to do the required 6200 mile lube jobs?

Just curious because folks think an annual visit to the oil change doctor is good maintenance.

[Will]

I have level 2 service done at Prevost on my way home after a long trip regardless the number of miles I drove. I think what is recommended by Detroit is 10K mile or every year.

[DON]

If I’m not mistaken, Liberty said that I could go 25,000 miles with the Volvo engine. I have had it changed about every 10,000 miles but have now decided to have it changed at every chassis lube (6,000 miles) because it will be easier for me to keep up with it.

Safe travels,

Mark

The Detroit Series 60 book for my 04 Monaco indicated 15,000 mile oil change intervals.

15k miles, see page 18 http://ddcsn.com/cps/rde/xbcr/ddcsn/DDC-SVC-BRO-0001.pdf

15k miles, see tables 2 & 3 on pages 58 & 59 http://www.ddcsn.com/cps/rde/xbcr/ddcsn/DDC-SVC-MAN-0039.pdf

I wouldn’t go 15k miles unless I was using a top of the line synthetic.

I go about 7.5k miles on good old dinosaur oil.

[Michael]

I think 10K is fine. My thought is if the company that builds the engine would just supply us with an engine manual outlining what the oil change intraval should be, that would take all of this guess work out of the issue we are discussing, would it not.

For what its worth……How many miles do you travel annually is the question…..Most use their coach and put 8-12k miles per year…If that is the case I would suggest oil change twice a year….Especially if there is a longer period of time in between use….So if the coach is not used for 3-6 months at the start of the season get a oil change and inspection, then by mileage…So even though mileage plays into it I want a oil change at least annually….I have seen a lot of coaches with 3 years since oil change, why they didnt have the mileage requirement….So be careful putting a drop dead number on services….

Even though nobody has asked here is my opinion regarding this entire topic.

From my perspective the people that really know what these coaches and engines need have said so in their setting of maintenance intervals. While an oil change interval may be 10,000 or 15,000 miles Prevost clearly lists a number of maintenance events at the 6200 mile mark. Prevost lists the oil change at 12,500 (or 12 months).

But nobody wants to say out loud that while they may be willing to change oil sooner than needed but longer than 6200 miles, they feel OK ignoring the 6200 maintenance events. Seems like a big disconnect. Getting under a coach for whatever reason represents an opportunity to do a lot more than listed maintenance because a quick undercarriage inspection in addition to performing work produces tangible benefits. You get to see leaks starting to develop, and some such as hub seal leaks lead into other expensive repairs if not addressed early. You get to verify the condition of the pneumatic system. You get to catch parts that are rubbing when they should not, you get to see possible damage from road debris, and parts that show signs of needing replacement such as shocks leaking.

What I have a lot of trouble understanding however is the sense that doing maintenance once a year saves a few bucks. Compared to the depreciation that is taking place on the average coach the cost of even the most anal maintenance program is pocket change compared to the true cost of ownership.

Jon’s quote from above…….

“Even though nobody has asked here is my opinion regarding this entire topic”

Guess we all believed you missed the thread, Jon.

Or either he was asleep Al !

Speaking of greasing the chassis. I grease everything else I own, but take the bus to Prevost. I guess I fear missing some. Is there a link I could be pointed to that would outline what all should be greased every 6,000 miles. Thanks.

[Bernie]

Eric,

If you pull up the service manual for your VIN or model year from the Prevost Car / parts and maintenance / publications they will have a diagram showing the locations of all lube points. Additionally I think in the same section there is a written schedule of the maintenance events and on that listing the specific points are identified by name.

But even without any diagram or listing, all lube points are obvious if you look at the joint that is moveable and feel around or look for the grease fitting. I spend a few minutes prior to actually greasing with some rags to clean any grit or dirt from each fitting and then when I am ready to grease the joint they are readily visible.

I do the lube of the chassis routinely because it is so valuable to do. A bad tie rod end for example even if only slightly worn can affect the tires or alignment. The U joints are working 100% of the time and greasing them is by far better than the cost of a bad or worse, broken U joint.

My earlier coaches had a diagram on the back door that showed grease pooints.

Ok boys and girls, back to my earlier post. That little book i was talking about from the manufacture spells out the maintance schedule they feel is best for their product. Ex. oil change….12,500 miles or 12 months. I think they know best..

If you have oil analysis done, you’ll know the proper change interval for your driving and you’ll catch other issues if they exist.
