It comes with free weinerschnitzel.

Curious why do you state that it is indeed better? What data do you have to support this claim? Aside from the 10w30 vs 0w30 which can be good or bad depending on your climate.

LSWannabe

Patman, you were running the short filter?

Patman

The reason I say this is after viewing quite a large number of oil analysis reports for LS1s using Mobil 1, compared to this oil. None of the reports using Mobil 1 have come close to the low engine wear that this oil shows. I also found the same drop in engine wear when I switched my sister's 99 Civic over to GC from M1. And many others on BITOG also saw big improvements in engine wear when switching from M1 to GC. It's simply a much better built oil. European oils usually are much better since they need to pass much more stringent specifications.

Patman

Yep, it's the only one I can run on the C5 since the long one would be way too close to the ground.

This also shows that if you're running the K&N oil filter, even the smaller version can do a fantastic job. I'd still run the longer one if I was able to though, since it'll hold more oil and it'll definitely flow better.

It definately does exist. The USA made good stuff was my first time out with GC. It was the week after first reading about the new american made stuff. I popped the cap to make sure it had a greenish tint. I didnt know it would almost glow irridescent green! Anyway, the label didnt have yellow in it like the normal american made crap, which was also mixed in on the shelf. Next time I went they had the made in germany stuff which had an almost identical label as the good american.

Since this stuff does truly exist maybe we should stop calling GC german castrol, and start calling it green castrol???!!!

So what oil filter should I use for this oil?

Patman recommends K&N

8-Pack

Its a 0w30, just says european car formula on the front, havent check the back to see if it is made in germany.

Its in his first post.

Whats the number for the long K&N?

Why is 0w-30 better than 5w-30?

Would a higher mileage car benefit more from a thicker oil, 10w-30?

I ask all the questions, because you seem to be the man at oil and LS1's.

LSWannabe

Long filter is HP2006.

Patman

The 0w30 flows better in extreme cold, but it's not necessarily the fact that this oil's got the 0w rating which makes it work so well compared to other 5w30 oils. A big part of it is that it's viscosity at 100c is 12.2 cst, versus 10.0 for Mobil 1's 5w30 and 10w30. Most other 5w30 and 10w30 oils out there are also close to 10cst too. This is why this oil would also be better for higher mileage vehicles. That thicker viscosity at operating temp means it will consume less oil and it protects the engine better at higher oil temps. This oil is actually very close to being a 0w40.

I think youve got your racial stereotypes mixed up. As unfunny as that was to begin with, its just been knocked down a few pegs. Not cause of the race thing, just cause it makes no sense.

I was wondering what he meant

Thanks for the info Patman. So a 0w-30 castrol synthetic is the way to go. Do you have a analysis of Mobil 1, in the same car? I am wondering if this oil is good enough to switch from Mobil 1.

A quick theory question: Would an engine using castrol 0w-30, see more mileage than an engine using Mobil 1 5W-30? Assuming both are drivin the same, and in the same climate, etc.

LSWannabe

Dont forget we're discussing German made Castrol syntec 0w30. Not American.

Patman

I switched my Corvette to GC as soon as I got it, so I don't have a comparison to Mobil 1 from this car, but I did run Mobil 1 and then GC in my sister's car, and engine wear was lower, especially the bearing wear.

In theory when you've got lower engine wear on your analysis, this means your engine will last longer. By how much, who knows? But I'd definitely rather see the lower numbers! Keep in mind too, that most people on here would probably never wear out their engine no matter what oil they run, since most people don't go more than 100k before getting a different car. But if longevity is your priority, go for the best oil you can find.
