I would say the quick answer is NO. I was told to not use 5W anything in a boxster. Much less diesel oil.

Why would you even consider this? the 80$ for good oil is much less than a new motor.

use redline, royal purple, motul, or even mobil 1 if you have to. Use the recommened weight for your location. I would call a local dealship and see what weight they use. I use 0W40 royal purple for the hot texas temp. I order it from Jegs online, and it is at my door in 2 days. You own an expensive car with a motor that costs big money to fix or replace. It is foolish to try to save money on oil, tires, or brakes.

At least you live close to Jake Raby, you will need him to fix your boxster when you burn up your engine.
