I thought there was also a 6 month rule, that it was against the rules to start one up again after that long? But I see it quite a bit.

Hey everybody! New forum member here who wants an opinion or two on motor oil for a 1963 fuelie. The car has a fresh rebuild on the motor (maybe 5,000mi) and I am looking for the preferred synthetic oil weight to use. Please be easy on me...I come from a BMW background and this is my father' scar. Unfortunately he has dementia and although this car is highly documented, there is no specifics in regards to what weight oil was used. Being a solid lifter car, I want to make sure it's properly lubricated. I have a few people to contact as of yet but I always like to get the opinion of the internet community. Many thanks in advance!

I am using Mobil 1 5W-50 bought at Wal Mart in my 67. 1100 PPM. Easy to find! Here is a pdf that shows what all the Mobil 1 oils contain.

Cited most often is that non-roller cam wear is reduced if the oil has high levels of Zinc/ZZDP. Valvoline VR1 has worked well for me. Certain diesel oils contain high levels and are often recommended. Look for a service rating of CI-4 or CJ-4...

Actually you want Mobil 1 15W-50W from that list - specifically designed for flat tappet applications. NAPA usually stocks it on the shelf....

i've been running 20/50 Valvolne Racing oil in my car for years.

The resurrector of this two year old thread specifically asked for recommendation for synthetic oils.

Maybe the OP has never read the owner's manual for his car. I believe it says to use 20W, 30W or 10W-30 and there was NO synthetic oil available back then or at least it wasn't recommended by GM.

Since he's used to the BMW stuff that uses synthetic, maybe he thinks it's REQUIRED? Why spend money when there's no need to?

Rotella T diesel oil is available in the viscosity grades as listed in the owner's manual.

I'm not sure using an oil with a viscosity range of 5 is a good idea if the engine was built to original factory spec.

I don't know if you're going to find a true full synthetic with enough zinc. Although just about everything out there is basically a synthetic blend labeled conventional anyway.

That's what I use in my original engine car. I order it online from Wal-Mart at $25.17 for a 5 quart jug and pick it up at the store with no shipping charge.

I use Amsoil. They have a special synthetic oil for classic cars with high ZDDP. I love it and I'm not an Amsoil distributor I will say upfront.
However, I got an Amsoil account so I order my stuff online and it is shipped to my door. Great product!

Post #3 sez it all.

As we have all painfully learned -- no one post ever "says it all" about engine oil. There are terabytes of posts on the forum on just this single topic I'm sure...

Or, you could really go overboard and use Harley Davidson "full synthetic" 20/50 motor oil. It's designed for use with their babbitt bearing engines - LOTS of zinc and phosphorus additives - 2% according to their specs, which is 2000 ppm.

It's only $12.95 a quart or $48.95 a gallon...........

When only the best will do!

Funny thing is, their spec sheet also says it's actually a blend of 60% synthetic and 40% petroleum oil...........

It pays - literally - to research a product before you buy it!

You sure about that?

I get a bigger kick out of bloggers having repetitive & overwhelming concerns establishing age of thread rather than contributing to it, just like expired milk... "Don’t drink it or your babies with be born naked" type attitude.. ha ha ha!

Oh and MikeM, I stated repetitive, same as tediously or repeating in addition to overwhelming so no need to extract an older thread that I post reminding you (only once) that it was an old thread.

MikeM

You've lost me. I don't care if it's an old thread or not. I read the owner's manual.

rustylugnuts

Touché.... Buuut engine oil has dramatically changed maybe not in weight but in structure many times since your 63 owners manual was created, Just saying...

rustylugnuts

MikeM

Just sayin' what? Start first with the proper viscocity. That hasn't changed even though the formulation has changed drastically.

Oils spec'd for old engines were spec'd for a reason. If they are built to the old spec, best the owner find an oil that meets those requirements. The requirements haven't changed either.

Based on what little I know about oil formulation, some of these oils being recommended here would fall short of the original requirement.

What else ya' got?
