What date was this issue. We haven't been any to find much out about them. They have been gone for awhile.

My understanding is the cabinet is still open I speak with his brother from time to time he had a conversion outfit here in AZ and the Magazine is from the 90's

Well I have said it time & time again!

When YODA speaks y'all should listen and learn!

We used to purchase Delo 40W or Exxon Xd3 40W (which ever our oil jobber had in stock @ the time we needed it, an if he had both we went with the cheapest!) by the barrel.

Upon reading one of Clifford's post about OIL here on the board I chose to do a little test myself.

I switched 1/2 the buses over to Mobil Delvac and left the other to on "what we had" and our oil consumption between oil changes dropped about 75%.

I now only use Mobil Delvac and buy it off the shelf at Wally World ! Or every now an then my local NAPA has it cheaper than Wally does!

Yeah, I lost all the docs down at Texas Custom Coach in Pipecreek Tx. when I was getting some goodies done the first of last year, and it had the original invoices in it. I knew there shop was still open for woodwork up north. Do you have or can I get a copy off the net? Thanks Cliff.

BK,
I assume that is Mobile Delvac 1240 you are referring to.

Walmart? Would love it if mine sold it

Lin,
FWIW I did the test on 2 strokes & Series 60s engines and it was Mobil Delvac 1240 sourced thru the oil jobber @ the time.

Also FWIW I am not running any 2 Strokes anymore and it's just plain Mobil Delvac 15/40 bought now days right off the shelf @ Wally World

Sorry for any confusion there guys!

But the fact remains the same with the Delvac we use less oil between changes on the 60 Series as well as we did on the 2 Strokes the test was done in 2009 when we had a pretty even mix of 2 Strokes & 4 Strokes in the 9 coaches we were running at the time! (thank god those are gone)

Yeah BK, Somebody told me years ago that those 2 strokes screamed like they did because they were always angry. Do they recommend a 15/40 mixture in these 8v92's or straight grade?

Scott & Heather · April 30, 2012, 08:26:03 PM

Probably straight grade 40

Busted Knuckle · April 30, 2012, 10:40:55 PM

muldoonman for many years they specified straight 40W. But over the last few years they have said that 15/40 is fine for the 2 strokes.
I'm just old school an still use straight 40W in all 2 strokes.

BK

Scott & Heather · May 01, 2012, 04:16:35 AM

Bk is right. Most of us stick to 40 wt becAuse we see less consumption. At least I do.

muldoonman · May 01, 2012, 05:51:13 AM

Folks, Thanks for the info. I will use what I got (delo100/40 wt.) cause i bought enough to change several times.

Thanks... The prevost 60 uses the Detroit oil and I was told not to change... My 6v92 I only use Rotella 40...

Did they explain why to only use Detroit Diesel oil in the Series 60? I've always used whatever bulk oil the local bus garage puts in and I don't burn any oil in my Series 60. I've never asked what oil they are putting in.

luvrbus · May 01, 2012, 08:32:53 AM

Some people just follow the manufactures recommendations and DD recommends the Delvac so does Volvo some like you really don't care what brand it is as long as it C-4 oil

I try and buy one brand and stick with it myself not that any other brands would hurt the engine just a personal preference for some

good luck
