Shell rotella t 15w40 is what i run in my 412. Its fine in colder weather, and has higher zinc than alot of oils. Just let it run for a few minutes before driving it.
Okay, I can find VR1 20w50 locally, is that too heavy? I've read lots of opinions. I really don't know much about the motor. It has a mild cam, and I don't think it was done recently. I have no idea though how many miles are on the motor in its present state, or even what it's present state is. It's a fair-weather driver.
I'd say it's too heavy for what you need. I have spun oil pumps with a drill with different weight oils, and it is alarming how much more effort it takes to turn the pump with 20-50 than it does with 5-30. I think G72Zed posted a napa part number for the 10w30 vr1. I know my napa couldn't find it on their own, but maybe they can with a part number. I will look for it now.
Thanks biker, you did post that for me earlier, I think. I will build up my courage and go into a napa, but as a former parts guy myself, have little patience for the typical parts counter guy lol. Haha, on a similar note, I went into the local gm dealer because I needed a door lock cylinder retainer as I'd misplaced my original. After telling him that I needed this particular item for a Camaro, the gm parts guy then asked me if it was for the front doors or the back doors.
Yes. It seems the whole automotive support industry has gone to the same operating model. Minimum wage, max profit, zero pride. I had to get the vin number for my son's duramax just to get a thermostat O ring. I feel the pain too.
I don't think the Formulations have changed unless they've been improved. Lake Speed Jr is still the guy behind this even if the company is based out of Memphis instead of Charlotte.
