Mobil 1 0w40
What do you guys think of running Mobil 1 0w40 in the summer & 0w30
winter I have .0029 on the rods & .003 mains std oil pump with Z 28 spring
Thanks
Ray

Re: Mobil 1 0w40 (CORKVETTE1)
Why not just run the 0-40 all year long? They start out at the same viscosity/pour temp anyway, so what's the point of using a 30wt during the winter .
Mobil1 0-40 is actually a little better than 0-30 as shown by some used oil analyses that I have read.

Re: Mobil 1 0w40 (JCAIRE2)
Your rite on that I just added the 0w30 I don't drive in the winter anyway
I ran 15w50 last fall 65 degrees it would have 90psi for 20 miles.
I change to 0w40 warm oil pressure @ 1000 is 18/20 @ 5000 it's 65 & stays
there to 6800 I'm :) :) :)

Re: Mobil 1 0w40 (Ray Vargo)
Multiweight oils use additives(polymers, etc) to establish viscosity index. Meaning, if you go from say a 10W-30 to a 10W-40, additional additives increase the range. Trouble is, additional additives displace lubrication oils. Single weight oils are used in several applications, providing maximum lubrication, temperature dependent of course. Some suggest using the smallest range possible, say 10w-30 vs 5w-30 or 0w-40, etc(GM used 5w-30 for EPA/mileage certification).
My preference is to use the smallest range possible, in my case 10W-30 for reasons stated above. For lawn mower engines etc, summer use, I use straight weights.

Your rigth on all that stuff but 0w40 is factory fill for Porsche,Merceds,BMW
& afew Japs. I have found with my set up .0029 rods & .003 mains pro mod
crank with H bearings the oil pressure seems to be in the best range
18/20 hot 65 from 5500 up to 6700.

:confused: so isn't a smaller range 5W-30?...So why don't you use 5W-30 if your preference is to use the smallest range possible?...not 10W-30 :confused:

He's referring to the difference between cold and hot viscosities; 30-5=25 or 30-10=20. 10-30 has the smaller difference between viscositie indexes.
Hope that clears it up.

Thanks..so is it better to use the 10W30?...because of a smaller difference between viscositie indexes?..if so I'll change to 10W30...

I'm not recommending that you try this in your Vette, but my M5 specifies 10W-60 :eek: :eek: :eek:

Re: Mobil 1 0w40 (Yello95)
If you go to the link I posted earlier, read some used oil analysis of 10-30 and 0-40 M1. Once you read a couple, you'll be able to see the analysis trends and decide for yourself. Personally I run 0-40 all year.
