HIGH IRON

[westex39]

I've been reading about high iron readings in overhead cam engines when using Mobil 1 and Mobil 1 EP. It also looks like the iron levels are lower when using a conventional oil such as Chevron & Havoline. Does anyone know what is going on with this?

Nothing going on with it. M1 EP is a very good oil. I wouldn't worry about the Fe levels at all. They are very low. Oil analysis is tricky in that you don't always know where the metals are coming from, what size and whether it's actually engine wear. Don't sweat it.

I have not noticed any Iron issues with M1 or M1EP in my OHC engines at all. I think that the so called valve train wear issue was with the old M1 Super Syn formula. M1 works great in most imports OHC engines especialy Toyota and Audi engine.I would not worry about excessive valve train wear with M1EP. I have not tried M1 since the EP formula was released except for M1 0W40.

Depends on the engine. I wandered in here checking replies on my thread. For example, based on a number of UOA's the Ford 4.0 SOHC that I have throws out a lot of iron. Iron read high on my previous truck with the same engine when I tried M1 0w-30 (for the winter) and much lower with M1 5w30. My new truck, iron was high with Motorcraft but much lower with Pennzoil Platinum. I'd say it depends on the engine, try some different oils and let the UOA's be your guide.

Thanks for your responses. Looks like I will go ahead with the Mobil 1EP for my 2006 Nissan Frontier and 2005 GMC Envoy.
