Bill is Excellence a person or magazine or what please elaborate i would like to see the write up.

 

Excellence is a Porsche dedicated magazine -- sold on newstands nationwide, or you can subscribe to it as well. It has lots of advertising in it, but it is a good read.

I've been subscribing to it since ~1996.

Hi,
this link may help with your oil choice;

http://www.landsharkoz.com/tt/ttlubricant.htm

The factory recommeded viscosities are 5w-40 or 0w-40 and the only permitted "heavy oil is M1 5w-50

The oil should at the least be a Group 3 synthetic, mineral oils are not Approved for use in any engine after 1973

Regards

 

Thanx for the link while very interesting im unsure how helpful it can be to me scince i drive a '78 924 with the 2.0lt vw engine

the other information is that for a 928 or 924 and how would i tell if the oil is group 3 synthetic

 

Hi,
most of the content in the link also applies generally

Most Group 3 oils are "semi-synthetic". Most Group 4 synthetics are labeled "synthetic" or "fully synthetic" or such. Group 5 synthetics are typically the most expensive (although the likes of Amsoil is a PAO Group 4 - it is simply overpriced)

Most of the M1 range is Group 4
Delvac 1 5w-40 is Group 5 (mixed fleet diesel/petrol-HDEO)

Beware using any petrol engine lubricant that does not have the ACEA A3/B3 or A3/B4 rating in any Porsche engine

Hi,

you asked the question - you got the answer!

Regards

 

well thanx for the info i did not mean to sound ungratefull. how did you come to poccess so much knowledge.

 

You're looking for SAE here in the States.

 

Hi,
knowledge in my case comes from excellent Engineering training in the Automotive Industry when young and then putting it to use for nearly 50 years.

Being self employed (Fleet owner in the Trucking Industry) for nearly 20 years and aged 66 helps a bit too. As well, three Engineer and a MD sons and a Lawyer (almost) daughter all keep me honest!!!

I worked on my first Porsche - a 912 - in 1967

I have learned from RENNLIST and I do hope I have helped others!

Streckfu's951 - the SAE handles the viscosity aspects (J300) of lubricants and the API handles the US (and some "International") Quality Standards
Check for the ACEA Quality Standard and Manufacturer's Approval data on the oil's container

Regards

 

i use valvoline max life 10w30

is that bad?? you guys usin some thick oil

 

Hi,

mgmarsh39 - Valvoline SynPower 0w-40 or SynPro 5w-40 are the only Porsche Approved and Listed Valvoline oils (WorldWide)

The 0w-40 oil should be used where temperatures below -25C are expected regularly (not likely at Daytona Beach)
