For the Porsches, Mobil 1 5w-40 Turbo Diesel Truck. Best value going for synthetic oil for turbocharged cars. For our JGC, Mobil 1 10w-30, but I'm going to increase that to either 15 or 20w, as it leaks a bit and I'm not going to bother pulling the oil pan to fix the leak, so the thicker oil should help.
Exactly. Why use something NOT recommended by the manufacturer?
Climate could be one, if you live in an abornmally hot area you may want a thicker oil, just the opposite for cold weather, you may want a bit of a thinner oil
Driving conditions,and age of engine determine what I prefer to use.In the south with warmer temps you can use regular 30 weight most of the time. A new tight engine needs the recommended type from the maker. When an engine gets worn the thicker oil helps keep the oil pressure higher than the very thin 5w30 or 10w30.

But the owners manual specifies the operating conditions for their recommendations. They might recommend a different viscosity for cold weather.

What the manufacturer recommends isn't always the best advice in all situations. If you live in Alaska, you do what you've gotta do to keep your truck running well in Alaska.

Are you suggesting that manufacturers don't know about extreme conditions?
