Suggestions for oil in a 347 stroker
« on: July 22, 2019, 03:08:21 PM »
Can anyone make a suggestion for the best oil I should use on a pretty recent 347 stroker?  What weight oil for now (summer) and what should I use for the winter?  Synthetic?
Thanks,

Hello Brian,

Depends, are you running a roller or flat tapped cam?

Cheers,

It's a roller cam.

We could go on and on about oils. It depends on what your tolerances are in the engine, roller, hydraulic, solid, what rpms, street, race, stop and go traffic, daily driver, freezing cold environment, burning hot summer temps, what you feel is a budget for high end oils? 95 percent of owners would fit the whats ever on sale at the local auto parts store, most all oils are quality oils today. Kinda like asking the crowd do these pants make me look fat? ;D Each person will have there own answer nobody right or wrong with their answers.

   Brian,
      A 5-30 or 5-40 should be fine for you engine all around. For synthetic "I" like Mobil 1. I have tried many "designer" oils without any 'magical" differences. On a low ( annual) mileage , weekend only car you can run the oil for a year without any issue, If it's clear enough to see the sick through it , it doesn't need to be changed.  I am not a fan of "designer" or "fad" oils. Others WILL have different opinions.

  Original Kendall GT1, Brad Penn , now DA lubricants ( green oil) is really good oil. It was recommended to me by Harvey Crane (rip) in the late '60 when I was having bearing issues with another popular brand I was getting for free. I have used it ever since on my personal drag race engines. It  is the best IMHO. The reason I mentioned Mobil 1 is Brian asked about a synthetic and Mobil 1 is a good one available everywhere. Brad Penn is a semi synthetic and harder to find.

I've been running Valvoline VR-1 10W-30 year round in the 347 in my 66 for ~10 years, no issues, send a sample to Blackstone labs at every oil change.  My cam is flat tapped, the VR-1 has high zinc levels like the good old days but if you're running a roller cam that probably isn't a concern.

    Randy, you should have known better than to use that Wolf's Head "Reconstituted Oil", you cheapo!   And then what, you moved "up" to Quacker State, pure Pennsylvania crud(e) with high sulfur and wax content and it's superior sludging capabilities?   You know, "the good stuff"; when you would pour a quart diesel fuel in the crankcase and run it before the oil change so the sludge might flow out the drain plug!     ::)

I do prefer "designer" oil myself.

Joe Gibbs to be exact.

Dinosaur oil for break-in, full synthetic for continued use.

      I don't know who's been letting out my secrets but here is the HONEST truth. As a teenager , I went to many races at LIONS ( rip) drag strip . The nitro dragsters ran an oil called RayLube. It WAS "rerefined" ( read used/filtered) oil !  Being a "dumb" young kid I asked one of the "big names" why. His reply was "It's good enough for one run and we drain it because it's full of nitro after that one run". At 10 cents a quart ( 1963-64 money) it made racing affordable. Yes I did run it at various times in "beaters" after I got my license a couple years later. We did allot of dumb things back then.

I am absolutely a Kendall fan. In the mid 80's in my Turbo it didn't burn it. When I ran Castol it smoked. Castrol also got thin quick.
I use Penn Grade break. It's straight 30 wt.  I run Penn Grade 30WT post. I use Dino in the FE. My other two Turbo vehicles call for 0-40 Mobil 1.
I run the O-40 during the cooler months and 10-40 warmer times of the year.

Re-refined oil. I love it! That's what I ran in my first vehicle - a 1960 Ford truck that got 50 miles to the quart. A trip to the beach and back on Saturday was a 2-quart run. Ten cents a quart was enough to pay for something that wasn't going to stay in the engine very long. What memories.

I have a 347, roller cam with Webers. I run Amsoil synthetic Z-Rod 10W-30 with Archoil AR9100 friction modifier additive. I'm in Jersey so my seasons are slightly limited but that combo suits the car for all my driving.
I made the change to the high Zinc formula after I mushed three flat tappets (that's when I changed to the roller cam too). Both the car and I are happy with this mix.

   The ONLY true way of telling if your oil choice is doing a good job for you is at teardown of your engine. if the bearings look like new and the rings are sealed , it's doing a good job.  Without a "CSI" , actual engine condition is a guess. My day job has me doing CSI on engine parts as often as once a week. Oil related causes amount to less than 10% of failures by "my" record keeping of failures "I" have looked at. "Oil supply" ( or LACK of) related problems are responsible for about 30% of what I see.
