BEST Ratings/Rankings For Engine Oils

Post by Sonny »

We're always looking for the very best oils for our Studebakers. Here is a list that has been done by an independent lab. It's self explanatory, just look for the highest PSI, ZINC, PHOS & ZDDP

ENJOY!

Here’s the ranking list:

Wear protection reference categories are:

*** Over 90,000 psi = OUTSTANDING protection

*** 75,000 to 90,000 psi = GOOD protection

*** 60,000 to 75,000 psi = MODEST protection

*** Below 60,000 psi = UNDESIREABLE

The higher the psi number, the better the wear protection.


1. 10W30 Lucas Racing Only synthetic = 106,505 psi
zinc = 2642 ppm
phos = 3489 ppm
ZDDP= 3000 ppm
NOTE: This oil is suitable for short term racing use only, and is not suitable for street use.

2. 10W30 Valvoline NSL (Not Street Legal) Conventional Racing Oil = 103,846 psi
zinc = 1669 ppm
phos = 1518 ppm
ZDDP = 1500 ppm
NOTE: Due to its very low TBN value, this oil is only suitable for short term racing use, and is not suitable for street use.

zinc = 1774 ppm
phos = 1347 ppm
ZDDP = 1500 ppm

26. 10W40 Valvoline 4 Stroke Motorcycle Oil conventional, API SJ = 65,553 psi
zinc = 1154 ppm

ZDDP = 1100 ppm

27. 5W30 Klotz Estorlin Racing Oil, API SL synthetic = 64,175 psi
zinc = 1765 ppm
phos = 2468 ppm
ZDDP = 2100 ppm

28. “ZDDPlus” added to Royal Purple 20W50, API SN, synthetic = 63,595 psi
zinc = 2436 ppm (up 1848 ppm)
phos = 2053 ppm (up 1356 ppm)
ZDDP = 2200 ppm
The amount of ZDDPlus added to the oil, was the exact amount the manufacturer called for on the bottle. And the resulting psi value here was 24% LOWER than this oil had BEFORE the ZDDPlus was added to it. Most major Oil Companies say to NEVER add anything to their oils, because adding anything will upset the carefully balanced additive package, and ruin the oil’s chemical composition. And that is precisely what we see here. Adding ZDDPlus SIGNIFICANTLY REDUCED this oil’s wear prevention capability. Just the opposite of what was promised. Buyer beware.

And the resulting psi value here was a whopping 36% LOWER than this oil had BEFORE the Edelbrock Zinc Additive was added to it. Adding Edelbrock Zinc Additive SIGNIFICANTLY REDUCED this oil’s wear prevention capability. Just the opposite of what was promised. Buyer beware.

37. 10W30 Comp Cams Break-In Oil conventional = 51,749 psi
zinc = 3004 ppm
phos = 2613 ppm
ZDDP = 2800 ppm

zinc = 1565 ppm (up 573 ppm)
phos = 1277 ppm (up 517 ppm)
ZDDP = 1400 ppm
The amount of Edelbrock Zinc Additive added to the oil, was the exact amount the manufacturer called for on the bottle. And the resulting psi value here was a “breath taking” 44% LOWER than this oil had BEFORE the Edelbrock Zinc Additive was added to it. Adding Edelbrock Zinc Additive SIGNIFICANTLY REDUCED this oil’s wear prevention capability. Just the opposite of what was promised. Buyer beware.

39. “Edelbrock Zinc Additive” added to Motorcraft 5W30, API SN, synthetic = 50,202 psi
zinc = 1680 ppm (up 573 ppm)
phos = 1275 ppm (up 517 ppm)
ZDDP = 1400 ppm
The amount of Edelbrock Zinc Additive added to the oil, was the exact amount the manufacturer called for on the bottle. And the resulting psi value here was 22% LOWER than this oil had BEFORE the Edelbrock Zinc Additive was added to it. Adding Edelbrock Zinc Additive SIGNIFICANTLY REDUCED this oil’s wear prevention capability. Just the opposite of what was promised. Buyer beware.

40. 30wt Lucas Break-In Oil conventional = 49,455 psi NOTE: THIS WOULD BE GOOD OIL FOR YOUR 500 MILE BREAK-IN - FOR 500 MILES ONLY
zinc = 4483 ppm
phos = 3660 ppm
ZDDP = 4000 ppm

Here's another.

Standard (old) oils, synthetics, additives, and some oil's with...additives.

Not easy reading, but a ton of breakdowns of oil by contents, wear resistance, hot wear comparisons, flow comparisons.
This guy's did this work and he's kept it going for years. It was started in 2013, and updated when he compiles new tests and changes accordingly. Some have challenged him on things and as far as I've read, he handled all negative challengers.
I go back to this work every now and again to see how things have changed. It's interesting to see how some manufacturers change their chemical composition, some get better, some get worse in some areas.

Again, it's ugly reading, and best done in sessions rather than all at once. You can also skip way....down to where the "chemical makeup" starts to where it starts to get interesting.

I use VR-1 conventional. Works great in my green car. I can get it at Rual King for $4.99. Close to half other places sell it for.
Thanks for posting,
