Budget Oils.
A local discount outlet is offering 15W40 part synthetic oil rated API SJ/ CF-4 at an excellent price. The 928 motor has by modern standards a relatively low specific output of 64 bhp/ litre. SJ oil is a big improvement on the oils available 20 years ago and recommended when the car was new. Is there any good reason why I should not use this oil as opposed to the much more expensive Mobil 1 ?

how often do you change the oil???
You really could use Dino for that matter, as long as it has the correct ingredients and its changed every 3000 miles

My three rules of buying oil:
1. Pick a good name brand synthetic
2. Buy a viscosity that fits your driving and climate
3. Stay away from all oil with a CF-4 rating
CF-4 is the "new" environmentally friendly rating with low ZDDP numbers to protect catalytic converters.
Do a search for ZDDP in every forum, there are many threads on this.

+1 There are some good dyno oils out there, like this:

The part synthetic oil is like the "beechwood aged" beer......the beer spends 18 days in huge aluminum tanks in a secondary fermentation near the end they toss in some beechwood chips (preboiled and processed to remove all flavor) which fines the beer causing all the yeast to fall out of suspension. Unless the synthetic mix states how much is synthetic it need only be a few drops in a barrel ! It is all just marketing.......save your money run plain old oil preferably with the ZDZP.

He said do not use it in any flat tappet engine like our 928's.
For what it is worth, I am no longer going to use it or any SM oil in any cars.

I'm just going to pass along one thought:
The price of oil is not going to be a significant part of your 928 maintance costs.....

The Valvoline Racing synthetic is supposed to be good also.
From what Mike said, more than a few of the manufactures are going to start making SL oils again because of the issues with the SM's

Every fall before you put your car in stoarge, take an oil sample and send it in*:

$22 and you might find out there is no reason to change it next spring.
*for us crazy bastards who live in the snow belt.
