Motor Oil for 2.4E MFI

[Stuttgart]

Greetings

I'm soon going to be changing the oil again and seek the good guidance of the club as to brands and type/grade of oil best suitable for a recently rebuilt 2.4 MFI.

I'm a little uncertain about the most appropriate type/grade given all the choices now available. Oils ain't oils.

Paul, I've tried Mobil and Shell synthetics and non synthetics in the past for my 2.2, but now use Castrol Magnatec Professional 15w/40. My engine is noticeably quieter and smoother. 9 litres cost me $76.50 from my local mechanic ( I think the "Professional" means its trade and in bulk).

Thanks Paul. Did you notice any new leaks when you used the synthetic stuff?

[John Shingleton]

I have a 1977 2.7 with a rather old engine which was filled with Mobil S( synthetic ) by PR Technology at the service they did on the car and it leaked like the Exxon Valdez . As soon as it was changed to Shell Helix by Cavaco in Glebe most of the leaks stopped . Carlos at Cavaco says old Porsche engines and synthetics do not mix as the synthetics get past old seals and my experience certainly bears this out .

I hear what you say. Some goose did the same to mine using Mobil, right after the rebuild. The engine was clean and re- powder coated. The oil burnt on the heat exchange, exhaust etc. It splattered everywhere. Very annoying.

Hi Paul, see John's comment, sure he's right. Since my top end rebuild a couple of years ago, I haven't had any significant leaks, but my view is that the older engines need the same period oils.

I've been using Fuchs Titan dino with no dramas.

John, thanks. I'll try and hunt some down. I'm assuming I can get it from Porsche in Collingwood - Melb.

FWIW Spencer at RRR uses Fuchs too (& now so do I!)

With a name like Fuchs, how could you go wrong

I've been using Fuchs oil in my KTM supermotard and am very happy with the performance. The bike is a 640cc single making 60 hp and the oil stands up better than the Shell stuff I first used with no appreciable change in engine noise and consistent gear shifts etc. Alot of bike guys seem to be moving to Fuchs but the bike shops generally only have modern synthetic stuff designed for bike engines with wet clutches etc. Anyone know a supplier in Bris for a suitable mineral oil for our old aircooled engines?

Cheers

Jeff, I last purchased Fuchs at Autopro.

I also have the details of the Australian importer of Swepco oil. Apart from their famous gearbox oil, they apparently do a very nice mineral oil suitable for older engines. If anyone wants the email contact, let me know - he's easy to deal with and just uses Aussie Post to get the oil out to you.
