Oh No! ...Not another oil thread ?

I have my asbestos suit on, so away haters...

Now, if your a dyed in the wool "My oil or nothin' " you are your own mechanic...but oil technology has changed considerably in the last couple of years when I was a firm believer in a particular additive to keep my Type 1 engines alive. ...but this is now, and things have changed , mostly for the better.

I found that really interesting, so much so that I bookmarked it for further in depth comprehension. Thanks for posting, I have 2 high mileage vehicles so this info will be put to use.

FYI : I spoke with Daniel of ...........

Oil Extreme International LLC
4216 State Hwy 57 N
Sturgeon Bay, WI 54235
(920) 495-7686 .............today. he and I had a good 30 minutes on the phone....his dime !

I asked about 'Prolong' additive and he said it was chlorine based which is not good subject to high heat, when it turns to an acid and eats iron. ( IIRC.)

Anyway, his chemists at his company discovered a chemical blend that when added at 2 oz per quart to 'most' oils, increases the film strength , as detailed in the link in my first post.

As a bonus....Daniel told me that the BMW Mini can have transmission problems in that 2nd gear cannot be engaged. His oil additive has cured that problem. Also, the shudder problem on some late model CVT cars is also eliminated adding Oil Extreme . I have no personal experience with this and only Daniels feed back on these transmission problems. However, the next Mini that comes by will have this done and see what the outcome is. Ill post it if it happens....or, even if it doesn't.....work, that is.

If you take the time to read 540 RATs blog you will see oils that are the highest to lowest film strength. I just changed the engine oil in my ML430 to MOBIL 1, the #5 best oil tested for film strength.....115,000 psi plus.

For a long time, I was a firm believer in ZDDP but the 540RAT blog has made me rethink my oil options and additives.

I have never been a additive guy as I consider most of them a waste of money. However when a engine shop here had 12, Ford 460ci natural gas station pumping mule motors on the dyno loose their cams after as short as 20 minutes, they eventually stopped the problem with ZDDP additive after being informed the new oils they had been supplied with are low in ZDDP from 1800 ppm down to 700 ppm or less, so Catalytic converters can be made to go 150,000 miles under new guidelines by the EPA.......among other 'benefits'. EPA is looking to regulate ZDDP as it can kill catalytic convertors.....they claim.

However, although they used a ZDDP break-in-oil, I have no knowledge of the oil they where using prior to, or after the engine cam/lifter problems....or if they still do. If you need to know who this company is, IM me and I'll give you their telephone number.

According to 540 RATs findings though, ZDDP is NOT REQUIRED to make an oil have a film strength high enough to stop break-in flat tappet lobe and lifter wear.

Indeed, he points out that incorrectly balanced amounts of ZDDP, in many cases, REDUCE the oils film strength.

However on one oil a reduction in film strength occurred when Oil Extreme was added, this was the case with 5W30 Pennzoil Ultra, API SM synthetic.

"..........11. “Oil Extreme concentrate” added to 5W30 Pennzoil Ultra, API SM synthetic = 111,570 psi
This oil on its own WITHOUT the “Oil Extreme concentrate” added to it, has a wear protection capability of 115,612 psi. But, with 2.0 OZ of concentrate added per qt, which is the amount intended for racing, its wear protection capability “WENT DOWN 3.5%”.
zinc = TBD
phosphorus = TBD.
moly = TBD
calcium = TBD
TBN = TBD............"

Now, it's for you to be your own mechanic and either take on this 'testing data' or not. Personally, I am going to try my next 1970cc VW Type 1 engine on the #5 best film strength oil in the test report. I shall pre-lub the engine as per usual with a quantity of oil slightly higher than normal ( 5 quarts instead of 3 and a 1/2 quarts.) just as I have done for 40 plus years on a brand new T1 / 2 and 3 motors....even before I was aware of ZDDP in the UK.

( We mostly used Castrol 20W50 GTX in the UK.)....a hang up from my motorcycle racing Castor oil days....amazing smell.

This higher oil level allows the cam on these engines to dip into the oil rather than the splash they normally get from the rods and main bearings. After about 15 minutes at 2000 to 2300 rpm, I drop the oil level to usual dip stick level and consider engine ready, if there are no oil leaks or other concerns.


If I have any more info ' I'll post it here.......

I have always run diesel oils,since my Dad's 62 S55 turned the odometer 3 times,and he got a good trade in.

" I'm shocked, you hear ? Shocked " No reaction pos or neg on the 540Rat blog ?

I am now switching to MOBIL 1 Advanced 5W20 this week and see just how oil pressures stand up and valve gear wears...or doesn't wear.

Have already put it in my ML430 and 'seems' a little different and MPG read out seemed to stay in the 20mpg range longer.....but that could have been wind direction the other night.

Been using Valvoline VR1 30W for a long time after loosing a few camshafts and lifters. Going roller in a VW T1 is way too expensive...well, for me it is.

I noticed all the diesel oils are rated at around 70,000 psi. Must be some reason the oil company lab's design it that way, but I don't understand why.

A lot of big rig engines use a lifter to plunge the injectors and have seen a few Detroit and Cat's engine go through a couple of camshafts ....they were all running Shell Rotella 15W40 without exception.

Only one engine had an antifreeze contamination in the oil.
We caught the wear from a Blackstone Oil Analysis. High iron.

They all went back in service with Rotella and covered thousand of miles.
