THE C350
Hi, I don't want to hijack the thread so please let me know and I'll start another one. I just picked up my c230 and was planning on running amsoil 0w40 (or 5w40) @ 10k change intervals here in a week or so. The place I'm going to take it to uses mann filters, is there a better filter I should pick up to run the 10k mile safely?

I'm not sure, amsoil has some euro spec oils and they are generally of higher quality (true synthetic) than most of the approved stuff, here is a link to the oil I was planning on using:
http://www.amsoil.com/catalog.aspx?code=AFLQT-EA
They also make a 5w40 that the local guy stocks so I might get that instead. I've had great luck with amsoil in my vette (not approved for that either
).

1999 CLK320 (sold), 2007 C230 SS (gone), 2000 Grand Marquis, 2011 CR-Z, stay tuned...
I'm pretty sure my car's used 5w40 since I've had it, and I know my CLK did. My dealership never used 0w40.

).Also the MANN filter is OEM so you can never go wrong with that

I made them use 0w-40 on my last service after getting way too much clattering at cold start, keeping in mind that my cold starts are 50 deg F.

No, AMSOIL does not make a 229.5 approved oil. The one that mdchaser is referring to is 229.51 spec'd which is fine for diesel not gas.
While AMSOIL's AFL oil is a very good oil, it is not approved for our cars. I am a dealer for AMSOIL and I can tell you that they are in the process of reformulating their 5W-40 European oil to meet 229.5 spec and also reformulating their 5W-40 Heavy Duty Marine Diesel oil to meet 229.51. You should use one of the approved oils in Glyn's Definitive thread here

Ok, ok, you've convinced me, no amsoil until they reformulate
. Could I pull off a 10k change using mobile 1 or castrol? I've always done 5k changes using mobil 1 on my grand am...

I changed Mobil 1 every 10-12k miles, when the SI told me to, on my old BMW M5 and had no problems up to when I sold it at 180k miles. When I went into the engine to change the timing chain a bit before selling it everything looked pretty clean and new inside. I was burning the same amount of oil at the end as in the beginning too.

I personally ran M1 0W-40 up until last change and have since switch to the Pentosin Pento High 5W-30 from RM European (On the Mercedes ROW approved list, meets 229,5 spec). The reason I switched is Mobil 1 0W-40 seems hard to find in my area, and is usually priced at an outrageous $7.99/quart. 2ea 5 Liter bottles of the Pentosin costs ~$70 shipped from RM European.

If you read this whole thread, you will see that based on Matt and mtnman82's UOA reports much more than 8-9K miles is pushing it a little bit with M1 0W-40 and paper filter on the M271 engine. While these UOA's are not a disaster with 10K and 13K, they show the oil pretty much shot at that mileage. I would say you should have no issues with 8K changes. The approved Castrol Eurpoean 0W-30 is REALLY hard to find.

I think I'll stick with a 7500 mile change with mobile 1 and a paper mann filter (both available here), it will be less expensive than an amsoil change so it should even out. Does amsoil make transmission and rear diff fluid that will work? If so which part numbers do I need?
Thanks!
