Short version: I used a Mobil 1 oil filter. Their website says it should have a check valve. Should I order a Mann right now, or will I be alright to wait until the next oil change?

Long version: Did an oil change yesterday on my new-to-me 240. I went for Mobil 1 full synthetic in 5W-30. I would have liked to use a Mann filter, but I didn't want to pay twice the cost of the filter in shipping. Instead, I used a Mobil 1 filter, thinking at least I would give the car something nice.

Well, after the fact I read about the check valve in Mann filters and started to get worried. I did some more research and found on Mobil 1's site that they install check valves "in the filters for those vehicles where the manufacturer requires it." So it does seem that I should be alright. Anybody agree? Disagree?

 

I've run them. no problems.

 

Run it. IMO as long as it has a check valve there really is no advantage to high end filters unless you are going to run really long intervals which I never do anyway. If you run full syn for 7500 miles or less the filter is not as critical as it is if you are running 10K or 15K intervals.

 

do NOT ever use Framm. They are total POS. Anything that is about the Mobil 1 quality is fine on the 240.

 

next time you're ordering stuff from FCP or IPD or someone, order some filters too, put them on a shelf for next time.

 

So much to agree with! You are fine with the Mobil1 filter. Fram is trash. Make sure to add-on some filters next time you're buying parts. I use and trust Purolator which are easy to find locally and I run short oil change intervals so not as critical.
