Hi to all you Porsche Classic People this is my first post.

So I put the 993 into the OPD last week and received quite a shock for the small service plus the pollen filters. Historically the cost on the job sheet has always been around £7 or £7.25p per litre for a litre of 5w/50. I always used to get the Porsche embossed pouch with a mobil zipper containing 1 Litre of Mobil 1. and a dip stick wipe.
This year the oil has been switched to 10w/60 and £14.70p per litre and no pouch. I know there was a shutdown of the manufacturing plant in Rotterdam from 2016 for the all new hydrocracker (Mobil 1) but that was in the name of efficiency. I was posting to know what everyone else's experience has been over OPD costs or Indie costs.
Can anyone explain why there has been a switch to 10w/60? when for the last 12 years it has been 5w/50

Porsche recommend their 10w60 classic oil for all aircooled cars with engines over 3l. Not sure how that affects the price though, but they sell it in nice metal containers, which I'm sure add quite a bit to it.

Because Porsche want to make as much money as possible out of their customers. As above, it's a marketing exercise to sell fancy cans, and lure the oil-cooled owners into more expensive everything.

If I were you, I'd switch it right back to the grade the engineers built the engine for, and in the UK climate, that ain't a 60.

As above. I've worked for Total for years within the lubricant division. Marketing departments exist for one purpose.

Thanks everyone,
I suspected Porsche would never give the technically correct account if asked the question. I would be listening to the commercial and marketing point of view. So its back to 5w/50 next year.
Once again thanks.

I don't doubt you, but which OPC has been using 5W50 for the past 12 years on your car?

Normally it would have been the same grade as the OPCs were putting in the 9x6 onwards - 5W40 or 0W40 back then.

Thicker oil has usually been recommended for higher mileage engines, so I'm assuming that's their reasoning, but it's a bit of a blanket approach as if your engine is in good shape there is no reason why suddenly you'd need to change oil grade.

Sure - but I'm guessing it's a 'low' miler - most 993s are hehe

That's marketing. They are anticipating that the cars won't be driven in the same manner.

As engines get older, you just need to consider changing more frequently with the manufacturer approved lubricant.

Hello Pete.

Then it doesn't matter what oil you put in it hehe

I wouldn't get too worried about it. I did an enormous amount of reading when I got mine, including the infamous Rennlist oil-threads, and asked many people oil questions; and then got bogged-down in the whole ZDDP changes to oil - but what it seems to come down to is just as the Total man says above - follow what it says in the Driver's Manual, which includes all of the grades here mentioned, except anything with a 60, choose a quality oil and change it as per schedule.

If you care, after 13 years of ownership, I've settled on Mobil Super 2000 10W40, taking into account all of the above, and I live in the South of the UK.

And more importantly over what some madman on the internet says, a 10W40 is what most/all Indys recommend? PHers please correct me if your Indy says otherwise.

I'm impressed that you have referenced ZDDP / ZDTP !

Manufacturer performance level every time, be that approval, viscosity, or acea/api and viscosity either way, regular changes trumps anything the marketers want you to believe outside of a race car.

I think you mean frequent. I regularly change the oil every 30 years isn't quite what you mean, I suspect.

Regular
recurring at uniform intervals.

Frequent
occurring or done many times at short intervals.

Confirm, that is what my independent recommends (also for the 996/7 cars).

10 w 40 for me too, and going back to the original post, that was £6.50 a litre (Castrol Magnatec)
