I'm changing brand of oil.

[Meat Head]

I would really like to hear an opinion from JFP in PA. In previous posts, he seemed to have extensive knowledge on the subject and have quite a bit of oil analysis on multiple Boxers that backed the Castrol being superior to Mobil 1. I would also like to know how he feels about the Castrol in the 5W 50 weight.

A lot of Boxster owners complain about start up noise (I do not have that problem). One of the reasons I stayed with the 5W instead of 0 is due to my belief that the thicker oil at start up may be adhering to the engine parts better. Just a thought.

From what I could gather reading previous posts JFP in PA works at a shop that keeps track of the oil changes and the results of the oil analysis after the change.

I'm sure JFP gets tired of repeating himself so much, why not search what he has posted on this & many other topics.
JFP recommends Castrol Edge 5w-40 (formerly known as Syntec)
Due to JFP & LN this was my oil choice until Jake Raby introduced DT-40 by Joe Gibbs. Ironically DT-40 only comes in 5w-40.

Not 100% correct. There is also a Joe Gibbs DT50 15W50. Good for the air-cooled Porsches.

If you read carefully you will see that not only is my statement 100% percent correct, but yours is irrelevant to this 986 thread.

Actually, unless he's changed his mind, what he has recommended (based on their UOA results) is the Castrol 10w-40.

I spoke with JFP in PA and he highly recommends Castrol 10W 40. Lucky for me, I hadn't changed my oil yet and the local Auto parts store allowed me to trade my 5W 50 in for the recommended 10W 40. I really respect JFP's opinion on this matter. He has a lot of background and research to back up his statements.


This weekend, the Box is going to get a belly full of fresh Castrol Syntec 10W 40!

one caveat, DT-40 oil is not recommended for Boxsters that see track use, not sure if that means autocross is also off the table.

Sure it is! That's all I use. I don't know of a better go anywhere, do anything oil.

That's not saying you can't find a better oil for dedicated track use.

PL is correct. Here is the direct quote from Jake:

"All of my engines that see even one day of track service utilize XP-9 and that product is only good for 750 miles before the additive packages are depleted.
So, in other words don't track your car on DT-40."

But thanks for posting the quote from Jake Raby to support my recommendation!
