Having been recommended by most to use Mobil 1 in my car, I went to Costco (where it is apparently cheapest).

Suggestion

I'm sure 0w40 would be fine in most 993s, but I can't see the harm in running a decent 10w or 15w oil?

Suggestion

Don't want to start another oil war ;-), but the 993's hydraulic tappets are a good reason to use 0-40 - they are often slow to pump up with thicker oils.

Suggestion

I generally use 15w50, but mainly because Halfords have some on the shelf and never seem to have the 0w40, so I don't have to make the decision.

If you all read your car manual, you will see that Porsche say that you can use any within the range from 5W -30/50 (Winter) all the way up to 15W - 40/50 (Summer).

Most of the tales of oil leaks when using these grades are on older motors not designed for them ...

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

14 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 2Original post

I would have thought so too, but some people reckon it's too thin, and the Mobil 1 Motorsport 15w50 is better. I generally use 15w50, but mainly because Halfords have some on the shelf and never seem to have the 0w40, so I don't have to make the decision.

POST 3Original post

You won't go wrong with Mobil Motorsport 15w50 or Castrol RS 10w60. Thinner oils you are taking your chances - will be fine for some but it will go through other engines like a laxative vindaloo.

POST 4Original post

Don't want to start another oil war ;-), but the 993's hydraulic tappets are a good reason to use 0-40 - they are often slow to pump up with thicker oils. Most of the tales of oil leaks when using these grades are on older motors not designed for them ... Cheers, Maurice

POST 5Original post

I also thought the variocam thing on later 993 models was designed for the thinner oils

POST 6Original post

It's varioRam on 993s - this is an induction mod. Not sure how oil could affect it... maybe it does? The 993 engine is based on an old engine design anyway. I'm sure 0w40 would be fine in most 993s, but I can't see the harm in running a decent 10w or 15w oil? Not an expert, so I'll shut up now

POST 7Original post

15-50 certainly recomended for 964's (ref: Conversation with Mobil rep at Goodwood FOS) and I always assumed the 993 engine was the same. Expect to pay nearly forty quid for a can. Melv >> Edited by Melv on Monday 7th July 11:59

POST 8Original post

I heard there were problems with Mobile 1 breaking down! I have switched to Shell Ultra 5w 40 on the advice of the guy who looks after my car - for what it is worth.

POST 9 / ORIGINAL POSTEROriginal post

Thanks for all the responses. As I will be at Goodwood Festival this weekend I will ask the proper questions there(to Mobil) and respond early next week on this site.

POST 10Original post

Dave -I spoke to a guy called Chris Horsfield. If any queries he suggested e-mail: frostm9mobil-europe-lubes.com. Don't know if that still current but u cld try. Rgds Melv

POST 11Original post

If you all read your car manual, you will see that Porsche say that you can use any within the range from 5W -30/50 (Winter) all the way up to 15W - 40/50 (Summer). It all there on page 82 of the 993 manual, check it out...

POST 12Original post

It's half the price in France. And I'd want to see some evidence that Mobil 1 breaks down. It's an exceptionally good oil.

POST 13 / ORIGINAL POSTEROriginal post

Thanks for all the replies. I did look at Goodwood but no Mobil stand and nobody else seemed to have a definitive answer. By the way the Carrera GT was something else and the light blue early RSR was rather smart too.

POST 14 / ORIGINAL POSTEROriginal post

Having been recommended by most to use Mobil 1 in my car, I went to Costco (where it is apparently cheapest). Grade of their Mobil 1 is 0W 40. Is that OK for a 993 or should I be looking for a bit heavier eg 5 or 10? Comments welcome. Thanks.
