The October issue of Panorama lists Shell Helix Ultra (5W-40) as the Porsche recommended oil for 993s.

I switched to Brad Penn 20W-50 this year from Mobil 1 (15W-50), but would feel more comfortable with a pure synthetic and one recommended by Porsche.

Is anyone using Helix Ultra?

Thanks

Personally I would stick with the heavier of the two choice, 15w50 or like you have the 20w50.

Where are you located?

I'll be using 5-40 this winter but will stick with 10-40 for summer time. I cant give you a specific answer on shell products though.... maybe charles can.

Hi Chris - I live near Chicago. I have wondered if the 20W-50 is too thick for winter, but the car is garaged and I was told it should be OK. My mechanic would also agree with the heavier weight oil in general.

FWIW, I blend Brad Penn 20W50 and 10W30 50%-50% to get an effective 15W-40. I checked with Brad Penn and they concurred that this was permissible. Seems to me to be a good solution. Less expensive than the synthetics and I change oil in my low mileage cars once a year anyway.

You are quite correct... Shell Helix Ultra is the recommended oil. I used it in my car without any problem.
