I use part synthetic but the other guys here probably know better.

I have read that synthetic might bother the seals on engines that were made for regular oil but it could be a myth.
If in doubt, use regular oil and just change when you are supposed to and should be ok.
I used part synth because that's all they had when i went for my last oil change.

I'm running Shell Rotella T6 5w40, which is a full synthetic. It's what I used on my first oil change in this car. I need to change the oil again, and I'll likely use the same.

Edit: My car is not a turbo.

Leaky seals from synthetic oil is not a myth. It only applies to 100% synthetic oil. That is not available at Wal-Mart or Discount Auto or any Jiffy Lube. In fact not even the Volvo Dealership uses it. In America full synthetic is Group 3 oil made from crude oil since 1999. I discovered this on MVS when my car had 140K. I switched to a true synthetic group 5 oil named Redline 5w30 and within 15K the rear main and cam seals which were original blew at different times pouring oil out then another 20K the O rings in the vvt hubs blew. So old round seals made of rubber like material leaked along with rubber oil lines to turbos over a 40K period of mileage after switching from Group 3 to 5. My car had 3K or 3 months whichever came first Dealership synthetic oil changes from new to 140k. The bonded seals like oil pan and cam cover are fine still original. My car has been in service since 12/2003 and has 215K. June

Yes, since I bought the first batch, of T6, I noticed it didn't seem to get restocked. Finally, it started getting restocked before quickly selling out. I actually bought another oil first, but then was able to grab a couple of jugs of Rotella since then.

When I noticed it being in short supply, I googled it, and found it's a problem with the supplier of the additive package.

Doesn’t it say in your book for the car what oil you should use?
I always run fully synthetic in every car we have.

Been running full synthetic 5w40 liquimoly for a few years now. No leaks, no issues, engine has 215,000 miles. Did the same for my xc90.

full synthetic 5w50 .
full synthetic 10w60
Is it ok to use these oils?
air temperatures in my area;
winter: max -10 centigrade
summer: max +35 centigrade
If we consider the engine wear for a vehicle with this shaft, I think that the viscosity of the engine oil used should be higher.
There are folks with more experience in this field.

Seems awfully heavy to me. Those aren't oils I've ever seen in the US.
