Been searching and the consensus seems to be that only the 0w40 Mobil 1 is recommended, but would this amsoil work with the crossfire? I live in a colder climate and will be winter when oil change time comes-

Signature Series 0W-30 100% Synthetic Motor Oil (SSO)

Inquiring because I have only run amsoil in past in my previous cars, and I want to get my supplies in order.

 

I think some of the MB guys use AMSOIL and Royal Purple.
I would guess that as long as it is fully synthetic, you should be OK (not sure about the different weight).
apkano or some other members may know better than I though.

 

I am currently running AmsOil 0W40 in my crossfire, on the second oil change worth of ams and absolutely love it, and will continue to use it. Much quieter than the mobil. I have not had any issues with it here in colorado, even during the winter snows. I even had an Amsoil dealer ask if he could take photos of my car so that he could help "push" the oil to some of the local oil change places. Lol.

 

To those of you in areas where they have "PEP BOYS" they have a coupon this week for $3.99 a quart, after rebate for Mobil 1.

 

I only use AmsOil, as I feel it is a far superior lubricant as compared to Mobil1, but I am also a hardcore car nut. At $8/quart it's like gold. https://www.amsoil.com/storefront/aff.aspx

 

Wait a minute...

In another thread you state that oil NEVER breaks down and complete oil changes are for fools!

What gives?

As far as using Amsoil...I see no reason that it can't be used, providing it offers the same protective values. (look at the codes listed, eg. SG, SD, etc.) Personally, I believe that the people who manufacture the engine recommend using Mobil 1 0-40, and they probably have a lot more in depth research done than anyone on the miscellaneous forums.

If it's good enough for them, it's good enough for me!

 

Thanks for the tip ZERACER, always on the lookout to get it while its on sale somewhere.

 

Oil doesn't break down, it loses additives and becomes contaminated, change the filter and add 1 quart. Otherwise if the oem filter isn't able to filter to 1/10 micron get a by-pass filter they also remove water from the oil... If you ever had the pleasure to cut open a screw on OEM filter from Toyota you will see they are not cheap as* pleated paper filters, but they are dense depth style by-pass filters, and now you know the secret of why Toyota engines last so long as compared to other manufactures. They are running by-pass filters.


Amsoil has a better shear strength than mobil1. and the manufactures have deals and contracts signed with mobil, that's why it's recommended. Mobil 1 isn't anything special, infact after you pour in a quart of Mobil1 I've noted that there is a thick brown sludge at the bottom of the plastic container of fresh mobil1, wtf gives? No way will I use that crap again!

 

Then how do you explain the sludge issues Toyota has had that prompted a recall of a huge number of both 4 cyl and 6 cyl cars?

 

I'm using AMSOIL European Car Formula Synthetic 5W-40 Motor Oil (AFL). It meets Mercedes Benz 229.31, 229.51 per the Crossfire Manual. https://www.amsoil.com/storefront/afl.aspx

I have a friend, who owns a garage, change the oil when he rotates the tires (on the B service schedule). Then I just switch the filter on the following A service schedule.

Between my Crossfire, Wrangler, Harley and girlfriends Crossfire I've gone from 9 oil changes a year to 4.

 

using non-synthetic oil in a high heat area, and i believe they didn't have proper oil return galley coming from the head, it was an engineering flaw in the head design. at least that's what i read.

on the 6 cyl motor used in the T-100 they had issues with the heads warping and some had bad head gaskets. but that was a crappy truck from the get go, it used many parts from GM vehicles, which is just lame.
