Castrol Syntec (5W-40)

Castrol's product is a Group III based oil. By the way, when people talk of Mobil 1's formulation change, they are talking about the fact that they went from group IV to group III. Not all Mobil 1 versions are made of the same base stock. I believe the some of the extended products are group IV.

What??? I have NO idea what that means! And neither the inclination nor the time to do the research to find out! I'm not bashing you, I just don't understand and, not being an engineer, not sure I would grasp the significance of it if I DID do the research. So...in layman's terms what does that mean? Is there any significance to me, the user, in what that says?

If you read through the sections of that link explaining the differences in the oil base stocks, it should answer your questions. In short, under most normal driving, group III synthetics are fine but not the best you can buy.

Against my better judgement and lack of time I read that article (or the part you referenced). Last sentence in the section reads: "To the best of my knowledge, Delvac-1, AMSOil, Redline, and Motul 5100 are the only oils made from pure traditional synthetics." Accordingly, one would assume that Mobil 1 is NOT pure synthetic.


The introduction paragraph reads: "I am not a lubrication, filtering, chemical or mechanical engineer. I have a degree in engineering, but I studied electrical engineering. I now study physics. You may feel free to question my abilities to gather facts and draw conclusions in the area of oils and filters. In any case, this is a write up of what I learned in about 75 hours of research on this topic. My only interest is having my motorcycle run forever, never break, and be easy to maintain." Based on his admitted lack of knowledge about the subject, I give virtually no credence to the remaining conclusions in the article.

So do more research and reach your own conclusions. I can tell you he is accurate in the descriptions of the oil make-up.

bobistheoilguy.com is a very extensive resource to start out with.

ARRRRRRRRRRR... I don't have the time, inclination, or KNOWLEDGE to do the research. You brought up a distinction which I admitted I don't know anything about, let alone the significance of it. And I asked you to explain WHY that was important. You pointed me to a source. Your source is severely lacking in credentials, by his own admission. Why would I believe someone who has a grand total of 75 hours of internet research on the subject??? Hell I can do that!!! If I was going to do my own research I'd need to devote hours and hours to it to derive any benefit, maybe. IF I could tell what it was I was actually researching. Time I don't have. Nor, as I've repeatedly stated, the knowledge of oil. Every discussion I've read here and elsewhere dives into technical lingo, rating of this and that property, etc etc. And I keep saying, so what??? What significance do all these things have, to me the user??? NO ONE will answer me. Everyone keeps saying.. do research. GRRRRRRRRRRRRRRRR NO I'm NOT going to do futile research to no end!!!. I've given up. And I've given up reading these oil discussions.

So there!

I'll use Castrol Syntec 5w40 and drive my Boxster for 200,000 miles!

Love Bob

Wow, I'm glad it's not my job to spoon feed you information. Maybe MNBoxster or Lil Bastard will come along and regurgitate some information for you.

^ doesn't the mileage have a large role in the peformance of the oil?
What I mean is if you change the oil frequently, well before it breaks down,
is there really little difference between a $5 and a $10 synthetic?

I tend to think it better to change your oil frequently with a respectable Porsche approved oil than to leave a more expensive oil in there for a longer period, long enough for it to matter.
