More about engine oils..

Place me in the synthetic camp, Mobil 1 for all my vehicles for, oh, 35 years. My experience and research leads me to the opinion that good synthetics cut engine wear by roughly a factor of ten. I even use Mobil 1 in my lawnmower...

The research referred to involved oil analysis at short intervals (on a modern car admittedly) to look at the levels of wear metals present in the oil. This was a crowd-funded independent project tragically cut short by the death of the project instigator in a car crash.

If you ever get the chance, compare the internals of a torn-down engine run on syn and one run on 'dino" oil. It's an eye-opener.

All that being said, I'm not brave enough to put syn oil in my A, as it hasn't been rebuilt in at least half a century. If I ever have it rebuilt to modern standards, with insert bearings and modern seals, it'll be run on synthetic for sure.

Pat Goss, who appears on PBS Motor Week, lives near me and had a weekly call in show on the radio here that I listened to regularly. While he typically dealt with modern cars, he swears by synthetics and says that they provide more protection in stress situations and do not break down like regular petroleum oils do. He essentially said the same thing that SAJ wrote above and he made a good argument I use Mobil 1 in my modern vehicles with excellent results and both of my Model As. Maybe overkill, but engine rebuilds are expensive and good oil cheap insurance. I usually get my Mobil 1 at Costco, which saves a bit.[/QUOTE
On national TV, Pat Goss once said, "THE MAIN ADVANTAGE TO HAVING DUAL OVERHEAD CAMS, IS THAT THEY ONLY TURN 1/2 AS FAST AS A SINGLE CAM"!
Point is: Don't believe everything you hear, even frum "EXPURTS":eek:

I can only comment on royal purple in a racing application. We have found that
it would break down with race fuel and become super diluted. Would I use it in my A hell no but I do use Mobil 1 ..15/50 and rotella 15/40 in A's.. I have never used a zinc additive as both products contain it in enough levels

Mitch.. Is the quantity of zinc the same in the Rotella and the Mobil 1? Do you agree the A engine needs some zinc?

No bridge images!!

15W-40 Rotella T with Triple Protection oil has approximately 1200 ppm of zinc and 1100 ppm phosphorus


Mobil 1 15/50. Has 1300 zinc and 1200 phosphorus


Zinc is important for any flat tappet engine..

Good one, Bill. This Goss guy must have been trained by "Click and Clack the Tappet Brothers"! They used to come up with some real zingers!
By the way, an "Ex" is a has-been, and a "Spurt" is a drip under pressure!

our local radio mechanic has been promoting syns for over 20 years in new or fairly new engines after first change.also claims 6,000 between changes.with crude oil down near $30.00 a barrel,i wonder if our motor oil will come down in price in the future? tom
 
I think it has a lot to do with the quallity of the hone job... Many factory brand new motors come with synthetic and are not run in before delivery... Most rebuilt motors are told to use reg oil first for break in.....
Any more thoughts on this
 
Before we put this fiasco to bed.. One more thing.

I emailed Mobil about their 10 W 30 syn for Model A engines and am waiting to see what they tell me. Bet it will be a gem of double talk..

Will post results.. If they even respond.. ;)
