Attention M42 motor owners: oil weight suggestions

[Mike Self]

The manual calls for 10W-40, but it's getting increasingly hard to find, especially full synthetic.  I can find 5W-40, but I'm an oil Luddite and am leery of 5 weight oil on anything other than door hinges.  Since I rarely drive the car in below freezing temps, how about 20w-50?

 

TIA

10W40 fs is easy (at least here). Try to find 7,5W30 that’s spec’d for Nissan RB26DETT. Never seen.

The last oil change for the BMW 318IS we used Mobile 1 Synthetic High Mileage.  Available on Amazon.

Been available since 1972 and the first to be tested and met the API specs of the day.

I just use the Castrol GTX 10-40 conventional non synthetic oil from war-mart. Works great.

In my M44 in my 318ti, I use Mobil 1 full synthetic 10w40 purchased at Walmart in 5 quart containers.  Works well for me!

[Mike Self]

Thanks, everyone.  10W-40 it is.  I'm partial to Pennzoil, and apparently they no longer make a 10W-40 synthetic, so will most likely go with Castrol or Mobil 1.

 

Cheers
