What Oil do you guys use

Discussion in '40- & 55-Series Tech' started by 77cruiser, Jan 17, 2007.

  1. Got a 77 with the 2f, pretty old never rebuilt but runs good. What weight oil are you guys running? 10w-30? or something better for older engines?

    20 w- 50 Shell Rotella AFAIK it does not have depleted levels of ZDDP, better for solid lifters & camshafts.

    I second 20-50w, it was the only thing that kept my oil pressure up.

    I've heard that this oil is great for older vehicles due to the zinc content for as you mentioned cam and lifters. It has been recommended for older big block vettes and I'm going to be changing over to it soon. (The Shell Rotella oil) I believe that it's a diesel engine oil.

    I think the area of the world you live in would have to figure into the picture. As well as miles on the engine. Exteme cold or high temps would seem to make a difference. Thicker oil seems to help with oil pressure as well with older engines that may not have been taken care of in years past. I use 20w50 but have more hot than cold. I think changing it regularly is the most important issue...

    I don't put high dollar oil in my FJ40. Instead, I use the Chevron Supreme 20w-50 all year. THese are tractor motors and not picky about oil. BTW-If you watch the ads, you can get the Chevron for $0.49 per quart after rebate. It's cheaper than gasoline. If I were lucky enough to get an engine rebuilt, I would run Chevron Delo 15w-40.

    The last oil change I decided to use Chevron Delo 400 LE SAE 15W-40 which is the same oil I use in my 6.5L turbo diesel.

    I was running 20-50w then just changed my oil and since it's winter I used 10-30w. That was a mistake. Before, I could keep oil pressure on my side better. Now I had to turn off the engine and winch pretty quickly when it was leaned way over. Obviously, I will be using 20-50w next time.

    Chevron Delo 10W-40 in the tractor motors ... don't waste your time with synthetic unless you've recently rebuilt. I use all synthetic in the 80 -

    20w-50 Castrol GTX all year but if it were cold I would run 15w-40. I am interested what oil pressure you guys running 30 weight oil are maintaining. That is a very thin oil for the clearances in these motors.

    Also. No problem starting up at -20F the other day. (Some guy with a "modern" vehicle said he couldn't start his because he had 10W30 instead of 5W30 and had to have his oil changed out. :rolleyes:)
