TWS > Redline, I believe Pal has been running Greddy for a bit and it was also reported very good.

If you change your oil as often as PAL does you can probably run EVOO although it would be a very expensive alternative. Since, like PAL, I track my Bimmer a lot my OCI is around 4,000 miles. My next fill will be with Greddy 10W-60 so we'll see what Blackstone has to say about that oil.

Why all the hate amongst the BMW crowd twoards redline products?
They have served me well with many cars in the past and especially ones that saw track time. I'm going to try redline and do a UOA to compare to TWS but, on paper Redline looks to be a clear winner. Compare the following and Redline has an edge over TWS: 1) ZDDP content (much higher in redline) 2). HTHS 3). 100C Viscosity

I plan to let a Blackstone UOA decide for me rather than digging through a bunch of opinions without a single UOA. I'm not here to argue the issue but, will post a UOA with driving conditions so members of this community can evaluate it as an option.

Call me crazy/stupid whatever. But I change it every 3K miles. A buck 25 is one less sushi lunch and it provides me with peace of mind. Over the top, etc... But...

Actually I'm surprised at how well it's held up, and was thinking that this makes a good argument for keeping the car. Just shows how folks draw different conclusions from the same data I guess. |

that maintenance plan will make the next owner really really happy, and perhaps, willing to pay you more

Part of my reason to switch is my local track(Road Atlanta) is a much better playground for high HP cars. I drove a friends C6Z06 on that track recently and while I loved the my M, I have to push it much harder to keep up pace which most certainly increases wear. In the Z I could short shift at 5k rpm and pass cars left and right. In the M that would require 7K+ rpm shifts in every gear, every time, and your right foot planted at every oppurtunity.
I think everyone here has made excellent points. I also agree with statements regarding repairs vs. track time. I'm willing to bet Z will be cheaper in the long run if track time is a factor. Well maybe if you don't count tires.

Sorry to necropost, but we just had a blackstone analysis of my dad's LS2 and he has lead at 22ppm, that's with 50k miles and only 1 autocross on the engine. We'll be doing a second analysis in a couple thousand miles since it's had another autocross since the oil was changed. I will post back with results.

On an S54 note I have 2k miles to go before the Redline 10W-60 goes in. I think I will be the first to try the stuff an do a UOA. Can't find ANY useful info on the M3 forum, just lots of argument.

Maybe that's why they say it's been discussed "to death" over there. Regarding ZDDP, since that's a major point of contention with TWS, they say it can harm the catalyst, but that there are other additives (titanium based) that can reduce harm to the catalyst. For our latest V8 build, we broke the engine in with diesel oil since it contains lots of ZDDP, maybe try to find some with the right viscosity and do a UOA on that as well? I know motul makes 10w60 diesel oil. Here's a thread comparing levels of P and Zn in a bunch of oils: http://wildguzzi.com/forum/index.php?topic=33841.0 And there's also this if you don't want to go with another oil: http://www.zddplus.com/ |

However, its too early(miles) to tell the outcome. TWS shears quickly and that combined with lower ZDDP MAY, acclerate bearing wear if only by a small margin. Bearings are protected by hydrodynamic film strength and ZDDP as a last line of defense. Redline has an edge on paper in these two specifcs, only time and UOA will tell.

But sounds like you just wanna run with bigger dogs. Shouldn't be surprising that a Z4M has to be pushed harder (or can't keep up) with a Z06. these cars aren't in the same performance league. |
