I have conflicting info on which to use. Had changed by local charter bus co and they used 40w. Have been told by others that should only use 30w. It is a 1962 pd4106 with original engine rebuilt with blower with only about 5k miles on rebuild. what's your opinion...facts? | ||

My DD manual says to use straight 40w. The local bus co. here put in 40w when I had 'em do the inspection. Opinions here vary.... why question what the commercial companies use, or what DD recommends? | ||

James I have been running Rotella T 40 wt In my Bus for about 19 yrs now, when I bought It In Albany Ny from the NY Yankees ball Club I asked what oil had been run in It and they told me Rotella T 40 wt they also told me that the Bus had been overhauled about 40,000 miles ago but It smoked a lot at startup four yrs ago I decieded to put new bearings In and the new ones didn't look any better than the old ones that I had taken out, so I am a firm believer In Rotella.

30 worksfine on Prudoe Bay and further north. For most 40 the DD recomendation is the best choice. The stick tranny will be happy with 30 , esp with a couple of quarts od synthetic tossed in. Your rear axle pumpkin is getting rarer , so treat it to an oil change with the next grease job. To keep the kingpins in the longest , jack up the front wheels off the ground before FLUSHING , not just adding some grease . Works for me , '06 The Sportscar of Coaches FAST FRED | ||

all the DD guys up say the same thing, use only 40W if the out side tempature never gets higher than 10* F during any part of the day or nite themn they use 30W which means that it is to cold to start with the heavy oil. as Fred and others have stated we use the 40W as DA book tells you. | ||

Yeah, And the idiots at the Truck Lube places will pump in 15w 40 if you don't watch them. They don't understand that a Detroit 2 stroke requires and needs that single grade 40wt CF rated oil. Specifically Marked on the label for use in Detroit 6V92 & 8V92 engines. Saw that yesterday on some oil on the shelf at Tractor Supply, But all they had was 30wt in the CF class. | ||

But. what is the best 40 w to use. And does changing from one brand to another [ at oil change ] make a difference to the seals or moter. | ||

On my 6V92T is a sticker that sez to use only 40W oil. With the cost of engine work, I don't want to experiment. I couldn't find 40W at area truck stops or auto parts stores. I did find and order the 40W oil from a farmers co-op that does a lot of work on DD in farm trucks and equipment. | ||

Hello James. I'm up in Canada, and I'm using 40wt. I have a webasto, so even with the temps down at 0 Farenheit, the motor dooesn't have any trouble turning after 20 minutes of 100 000 BTU into the coolant. In the days before Webasto (would that be BW?) when the motor had to start cold, using the dreaded ether, the lighter oil made a difference for getting the motor to turn. Further north, where the only rule is survival, they ran 20 weight in the really cold, and just kept adding oil as it burned it. My motor stopped smoking and consuming oil after I did my first oil change. There was "something else" in there before that. You will most likely have to find a source for it at a full line parts place, or your local DD shop. The two stroke DD is getting pretty rare out on the road commercially, (in trucks) and many busnuts report difficulty in finding it on the shelf at a truck stop. (bus folks keep to themselves, rarely seeking service or supplies from truck vendors) Many of us keep enough supply on hand at home for an extra oil change, and take enough with us on trips for top-ups, as you might not find some locally on your travels. happy coaching! buswarrior | ||

I'm fortunate the Shell station near us will special order the Rotella straight 40w and give me a case discount. |
