Oil Viscosity

[diondion]

I am changing oil for my '73 2002 til - recommended oil viscosity; good oil brand out there?  Thanks

[FunElan]

Most people will say they use 20w-50 with a few exceptions...I use Castrol GTX high mileage

Hang on.  

I'm making popcorn ?  for this one.

+1 on 20w-50, unless you're running it in very cold weather (below 25 degrees or so) on a regular basis; then use thinner oil until the weather warms up.  Been using that weight for 25+ years with no problems and plenty of oil pressure, even on a 225k mile original engine.

 

I've been using synthetic in my '73 since I rebuilt the engine, either 20W-50 or 15w-50; Amsoil and Pennzoil respectively.  However, Pennzoil no longer makes 15w-50 synthetic so I guess I'll go back to Amsoil.

To quote FAQ user peterschop:

 

"For motor oil, you will want one with a high ZDDP content such as Valvoline VR1 20w50 racing oil. Brad Penn is also a good one. The old motor oils had it in them but most of the new formula oils had it taken out because it will ruin the catalytic converters. Flat tappet engines like the M10 motor need the ZDDP to protect the camshaft from wear."

 

I got mine on Amazon.

And search the faq.  Probably 1000 threads on oil.  

 

To answer your question. Most will say 20w-50 oil with zinc in it.  If your motor isn’t freshly built synthetic probably isn’t great for it as it usually leaks more and has more blow by.

 

i use Valvoline VR1 mostly because of the zinc.  I have had a rebuild recently so I tried Mobil 1 15w-50 synthetic (which also has zinc in it) just to see how I like it and I didn’t notice a huge difference. 

 

Used to to use Castrol 20w-50 but they removed the zinc from it.

You should have one of these under the hood.

asking "what oil?" on any car forum is like asking what religion is better.  there is no right answer.  use any brand that has the viscosity specified in the manual.  and change it at the specified interval.

Ahh. The good ol' oil debate  

 

Jr, which Castrol were you using? I've been on the Castrol Classic 20w50 train for a while and seems to be just dandy.

Uh...  This is a reprint where someone didn't understand plus and minus?

 

OT, using the VR1, seems fine.  Engine burns / leaks so much that I'm starting to just use whatever I have laying around to burn through it.  (Engine is getting ready to get rebuilt...)

I've never seen the Castrol Classic line, at least in my area of the USA.

I buy as much Valvoline VR-1 20W-50 as they have from whichever big box auto parts store has it on sale.

Yes, be careful what you buy. This came as part of a set off Ebay a good while back. The fuse sticker was also bad.
