Oil Change to Brad Penn - Less Leak, more Burn
#46
I never said forum experts, I didn't assume anyone on here was an expert from the oil industry or from Porsche. I simply implied "rational" advice, i.e. regardless of opinion, its weighted in favour of Porsche and Leading brand oil companies instead of others, or as Perlfather put it, "experts".
I don't favour one brand, i use all sorts in cars, I just can't believe that the oil industry and Porsche are wrong and a few engine rebuilders are right. but thats just me...

It would be funny if Porsche came out and said ,
none of the new motor oils that the feds have degraded the specs on ,
meet our requirements for our older motors .
The thing is they do not want the old type oil in the new cars , the new cars don't need the old spec oil . The new oil is better for the environment .
The feds said the the new specs for the oil (sm) will be such and such .
The people who make cars built the new cars to run on (sm) oil .

I understand what you are saying, Thats very possible, but many oil companies in Europe make car specific oil: VAG long Life, Jaguar Long life, Ford and even GM specific oil. Although Shell now make an Ultra Extra oil which meets or exceeds all the different oils supplied to the car manufacturers for their individual oil requirements and many garages are buying this. although due to "refining and additive shortage" it is on back supply at this time.
Couldn't Porsche and Mobil (being partners) make a specific oil if they wanted or felt it was necessary for all 911's or 993 and older?

Do you have some information / tech facts on this oil?
On the Shell website it doesn't say much about long life additives for older engines and unfortunately there isn't a caution that it could reduce catalytic converter performance (which is usually good news for us, I think).

I work for a company that supplies Shell, Mobil and Castrol and Comma to the automotive trade industry, so I tend to read the literature and speak to Reps at some point, "meets and exceeds" is the script used in most oil literature these days. That oil won't be suitable for our cars it was an example for the discussion only. This is the link, Shell Ultra EXTRA but as i say its not relevant. http://www.shell.co.uk/home/content/...x_ultra_extra/ Its a low SAPS oil so protective of Cats.
The correct oil (just spoke to Shell Technical again)
The Shell Ultra 5w40 catalytic compatable, approved by Porsche/Ferrari (not low ash spec either)
http://www.shell.co.uk/home/content/...w/helix_ultra/
But I understand some may still think its not good enough, even if its approved. Each to his own I guess...

"Founded in 1881 at the height of the domestic oil boom, the Bradford refinery is the only refinery processing 100% Pennsylvania Grade crude oil. It is also the oldest continuously operated lube oil refinery in the world."

I can't tell you all that was said, but they were amazed that anyone would put that oil within a mile of the Porsche engine without proper testing and cooperation with the car engine manufacturer.
But as I say each to his own...

The way I see this oil issue is this. Today's new Mobil-1 oil is for today's new cars with their newer technology. Yesterdays cars had yesterdays Mobil-1reccommended for it, but they no longer make the old formulated Mobil-1. So the issue is do we use today's oil that was not designed for the older cars or do we use an oil that still has the additives that were designed for yesterdays cars? To each his own but my feeling is that the Mobil-1 formula that is produced today was not around in 1990 when my engine was made. That is why I use Brad Penn because it is still made with the specs that are necessary for my engine where Mobil-1 isn't.

@SML Porsche pretty much only approve a 0w40 or 5w40. But like all things it will depend if you track the car or not, if the engine is in good condition or not and also your climate.
Some lists (I can't account for the validity)
http://www.wrightune.co.uk/downloads/approved_oils.pdf
http://kiyor32.cocolog-nifty.com/gt3...-List-2006.pdf
A40 approved, listing PAO synthetic group IV oils. Ester/PAO synthetic, group V oils. Specs are backwards compatible so improve, however you could contact you local Porsche dealer for the latest list or their own suggestion.
My personal opinion is the 0w40 or even the 5w40 is possibly a bit thin, unless your engine is in top condition or you race (requiring some 0W & 5W oil that are group V Ester oils so they are of a higher spec and to prevent oil drag). But I might change to a 5w40 at the next change. 10w40 full or Semi would be a good choice too, not fussed on brand as long as its a leading oil supplier Shell, Castrol, Mobil etc and approved.
