Thank you leftover Pizza, I mean Pizza to-go, I mean pepperoni Pizza. Damnit! You know what I mean, Thank you.
Along with 'zero4crossfire's link (https://www.walmart.com/ip/Castrol-E...5-QT/145736795) you have moved some oil off the shelf today!!! And, also, sell your stock in Mobil 1. Yeah.

 

Mobil1 0W-40 is on sale right now at Walmart for $22.88 @ 5 qt ( https://www.walmart.com/ip/Mobil-1-A...fc017e0a0ab7b7 ).

What Valk said, and bought from Walmart at $23.99 a jug.

 

LOL, love all the money everyone has..SUPERTEC, half the price and meets/exceeds MFR rec.. Used on all my cars including several Vette's since 2005.. Save your $$$

 

My other two vehicles use ST, I never saw a ST oil that has the MB spec on it yet though. I have a limited lifetime powertrain factory warranty on my 08, would not want to be denied coverage because of some obscure technicality! Wal-Mart Mobil1 0W-40 synthetic for my girl!


.

 

What good is a lifetime warranty when the expertise and infrastructure no longer exists ?

 

 

Enjoy and spend. On flip side I never heard a MB as the requirement (not recommendation). As long as its meets/exceeds the Specs which ST does....Ill use it all day long. Too bad I cant get a ST oil filter (I use them on all my Vette's)...Hate Oil companies-they put fear in you..

 

Good question, and I'll find out the answer when an event happens!

You are wrong young patawan! The recommended oil for the German built Crossfire, 3.2L motor, DOES have a European spec for the oil (recommendation). You can do whatever you want with yours, I'll spend what and where I want to. You probably bought yours USED, huh? Whole picture here vette guy!

For those interested in using Castrol Edge full synthetic 0w40, I found it on Amazon today for $19.31 per 5-qt jug. Pretty good price! Free 1-day delivery if you are a Prime member.

 

Yeah, GOOD PRICE! Does it also ship free if spending over 25 bucks? You do know they have a disclaimer about shipping times @ the virus? Also, I am guessing it is euro spec for MB spec's for the XF?

This is good info describing multi-grade oils. What I like to remember is a multi-grade has a "flatter" viscosity curve versus operating temp than a single weight oil. In other words, with the use of additives, the oil companies can enable an oil to better maintain its viscosity with increasing operating temp.

 

Oil meets the 229.3/229.5 MB Spec. Price may be somewhat normal for this brand/grade. Saw on Walmart's website 5-qt jug was the same price. When I changed the oil/filter on my Coupe a couple of weekends back, I had several quarts of 5w40 Castrol Edge Full Synthetic in my stock. Oil is approved for the VW Beetle (interesting, don't think 0w40 is recommended). Anyway, I used 3 qts of the 5w40 Castrol with the 5-qt jug of Mobil 1 I bought.

 

Ok, let me take a stab at summarizing the engine oil advice:

• Full synthetic only
• Meets both Mercedes specifications MB-Approval 229.3 and MB-Approval 229.5
• Although our cars' documentation specified 0W-40, 5W-40 is an appropriate substitute
• Use a high quality oil filter (e.g., Mann HU-718/5X)

Based on a bit of reading it appears that the 229.3 specification applied to pre-2005 MB engines and 229.5 applied to 2005 and later engines. There is ambiguity about whether the switch over model year is 2004 or 2005. (And aren't our Crossfire engines pre-2005 MB ones?)

Links to the current MB oil specifications:

• https://bevo.mercedes-benz.com/bevolisten/229.3_en.html
• https://bevo.mercedes-benz.com/bevolisten/229.5_en.html

Note that these specifications claim to apply only to engines in current production. There is also some MB forum chatter about MB oil specifications and paper/non-paper oil filters, but it looks like a rathole.

There are only two 5W-50 oils that meet the 229.3 specification, both are Mobil 1. 5W-50 does not appear on the 229.5 specification, but that might not matter based our engines being pre-2005, though this thinking may not be correct.

[Me: I've been using Mobil 1 0W-40 with Mann filters. When I run out of Mobil 1 a few years from now, I might switch to 5W-40.]
