40 weight oil getting impossible to find

[Coloradobus]

Lloyd, we go to a local lubricants dsitributor for our Delo 100 SAE 40. Its running less than 15 bux a gallon, and has a higher flash point than the Delvac 1600. the info specifically states use in 2 stroke Detroit diesels , where the Delvac does not.

Tuga we pulled the pumps and tested them for water flow and then burped the system. We have a Webasto and the previous owner lived in LA and never used it (the toe kick heater were enough and easier to use). Joe ran enough coolant through the system to finally flush out all the air. That seems to have been the problem all along. The only air bleeder we could find on the schematic or the lines was at the Webasto. We never could find one in the bus.

Jim thank you for the info.

Thanks everyone. I found a place in Indianapolis to get some and we are heading there Sunday. I will have to start going to more Detroit shops, because Napa, Auto Zone, Advanced, and Walmart are not stocking straight 40 anymore, at least not at the stores we visited.

Lloyd:


Good evening. I know you two usually stay at one spot longer than we do. Reason I mention that is because our small town local NAPA store has always been able to get me as much Rotella T Straight 40 weight as I need, even though they do not stock it. Gallons usually about $11.89. They don't carry it, but will order it for me and usually have it next day. I know you now have enough on board for your next oil change, but in event you find yourself needing some on one of your "extended stays" somewhere, NAPA might still be viable option.
