04 Grand Am GT. Mobil1 5w30.

Hey all,

Thought I'd post my first of many to come Oil Analysis.

This was done on about 4900 miles with M1 5w30 full Synthetic w/a K&N Oil Filter. Just under 80,000kms on the Odometer, and a few Drag racing runs aswell.

Your air filter may be to blame for the elevated bearing wear metals. What are you using and how long has it been in use?

Your engine is not new so we can't attribute the bearing metal levels to break-in. Also can't attribute it to running the oil too long.

Air filtration could be an issue. I see manganese, are you using a fuel add? That could cause the high lead.

Canadian gas, from what I've read, elevates 'Magnese' levels in UOA's b/c of the formulation used up here....don't know the specifics of it....

Duh, I should have realized that. It's MMT. Doesn't MMT cause bearing wear though? In the UOA's I have seen with higher levels of manganese there was associated bearing wear.

Is there a way to get some gas in the Great White North that doesn't have MMT in it?

My Air filter was really old. A K&N Cone style for my Aftermarket intake. I replaced it shortley after the sample was taken. I have another ready to be shipped out.

Fuel used is Sunoco 94 Octane. I sometimes toss in a bottle of STP Octane booster when I go to the track. (Which I did with during this sample)

What exactly is MMT?

MMT: MMT via wiki

Replace intake filter, run a short dino OCI as a flush, try M1 again.

 

[Laminar Lou]

MMT is a fuel add that raises the octane of a fuel. It is hard on your EGR and Catalytic converter. I think it is banned in the US, and I know it is certainly banned in California. It's full name is Methylcyclopentadienyl manganese tricarbonyl

MMT Wiki

What air setup did you switch to. The K&N is probably your source of the silicon.

 

[slowbird]

Ahhh...I see. So the High Manganese is most likely from the MMT in the Canadian Gasoline, and the High Lead content might be from the fuel additives?

My Intake Filter is new and I plan on doing a quick crankcase flush.

You've all been real helpful. I've read the forums on here awhile now, never had an excuse to post until now.

Thanks!

I'm running a Short Ram Inatke setup with a K&N Cone. The intake has a heat sheild on it between the Engine and Filter.

My guess would be the octane boosters are causing the lead, but I am an amateur at best at this game. The lead doesn't seem high enough to worry outright, but it is elevated. If it were my car, I'd stay away from the octane boosters and see how your next sample looks. I doubt they really do anything for you anyway in a modern engine without mods.

Just my 2 cents.

 

[slowbird]

I'll ditch the additives and see how it goes.

My next sample I already took so we'll have to wait for the 3rd analyses to see if the Lead drops.

Being an owner of an '00 Grand Am GT, I don't quite understand the 94 octane. It says in the manual that 87 is all that is required. I ran a fenderwell CAI for a while and 87 still did just fine. I'd fill with the correct octane and also drop the octane boosters if all you're running is an intake and possibly an exhaust.

Canada does not use MMT.
