hey everyone, i just picked up an 87 sdl in pretty good condition. I'm wanting to do an oil change but i want to make sure i've got the right oil. Anyone know if mobile clean 5000 is fine, and does anyone have info on the correct SAE specs that Mercedes says is ok for these cars? I've looked in the owners manual and in the service manual and cannot find anything on the SAE specs. Thank, happy holidays

The Holy Trinity of diesel oils: Dello, Delvac, Rotella – all 15w 40, all will do fine. An OEM filter IS A MUST.

my oil

My mechanic who was the previous owner of my 87 SDL (265,000) used Rotella 10W-40 but I switched her to Castrol Syntec 10w-40

after 340,000 (and still running like a top) in my Beetle TDI - it's got to be good!!!!
