What Oil do you guys use

[cruiser88]

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. )

maybe he should run vege oil .running castrol oil right now

1976 FJ 40 w 69k miles
10/40 Castrol GTX.

Oil pressure is pegged on the needle.

Hi All:

I have been running Castrol 20W50 in my FJ40 (2F) for the last 7 or so years with no problems to report. I think 10W30 is too thin a grade of oil for an older design engine like a "F" or "2F" unless it was really cold!

Regards,

Alan

valvoline 20w50

 

[wesintl]

of course 20-50 year round but i gotta say at 0 here in denver lately that stuff doesn't help my f turn over....

 

[lc69hunter]

Valvoline or Castrol, usually 10w-40, though since I rebuilt the 77 2F (to fairly close tolerances), I have been running a semi-synthetic after the 3000 mile break in.

Castrol 20-50,even though it is almost $3/qt. I've used this in anything that resembles a truck engine since the first time I changed my oil as a kid. It works well (not like in my nissan that require 5-30W for the VTC to function properly in the cold)

 

[wantatlc]

10-40 year around from Pep Boys for my SBC

 

[Jake40]

20-50 castrol

 

[tlcruiser66]

Castrol 10W40 all year

 

[landcrusher909]

20 - 50 for the last 15 years

 

[froggy]

pennzoil 20w-50 all year

 

[Cruisertime]

Redline
20W-50
10W-40
5W-20

 

[Clyde-2]

20w-50w Castrol with a bottle or two of Shiner Boch.

I wouldn't put Penzoil on my bicycle chain.

i try to stay away from oils with such a large span in viscosity such as 20w50 because they have to use so many polymers to "fill the gap" and that sort of leads to thermal break down and an oil with the least polymers is happier engine.

So what is YOUR recommendation?

So what is YOUR recommendation?

lol is everything i say on these forums wrong poser? lol
-i'll go back into hiding


i run 10w30 synthetic either pennzoil or mobil1 because of there higher then normal zinc content. but thats in a 350

-just my .02

What Oil do you guys use

New, clean oil.

 

[JohnnyC]

New, clean oil.

you put new oil in? and its clean? maybe i've been doing it wrong all these years... note to self use clean, new oil

Hardly worth taking personal or getting defensive about.....


You were expounding on a supposed inherent problem with “ large-span”, multi-viscosity oil and did not give any recommendation on what you suggest to use instead.



I have seen what the combination of lightweight oil and low oil pressure does to bearings in a Land Cruiser six; I will stick with my 15W40 or 20W50, thanks.
