Did you ever get a clean answer on this? I too bought one off RockAuto, as it listed it for my '17 5.3 V8 Silverado. I don't have any issues that I'm aware of but now see that this filter is for the V6 (Hi Feature V6) per the following: Today's engines have very tight tolerances, multiple oil...

I too have tge ZF 8 speed in our X5. I do a drain & fill @ 60k, then again at 10-15k. This will refresh your current fluid, to get rid of clutch material particles & replenish due to heat wear on the fluid. If you buy your fluid from FCPEURO, they will honor their lifetime warranty.

How many miles on it

Fyi, I too use a car filter on my B&S 21hp engine on my JD mower, a Purolator PL10241, which has same threads & pressure bypass psi. I just remove the filter & pour out the fluid in it & replace it every oil change. These filters are good for 10k miles on a car so 10 hrs a year is nothing.

If seal starts to leak, add 1oz od AT-205 for each qt of gear oil. Stopped my leak.

If it were me, go to RockAuto & see what they offer in AGM batteries. Best price & warranty

Interesting idea. I was thinking the same I was thinking the same thing as you. My thoughts are.....all seals that I have replaced in my cars were very hard. like hard brittle plastic. They leack because they are hard, they shrink & allow oil past. I use High mileage oils & they don't seem to...

I most certainly understand & respect your discission. It is a big investment & needs to be taken care of more than most people want to put the money or efforts into. I'm just curious about how oil filters are affected after...say 5000 miles of filtering. Is it 1% or 80% restricted?

I understand your point but that's not what I was looking for or asked info on. I'm just an old engineer curious about oil filter flow rates after 5k-10k miles.

I'm curious, has anyone ever scientifically tested the flow difference on a used oil filter as compared to a new oil filter, to see how much flow is actually affected after 5k or 10k miles? I've read so many threads about guys complaining about "bad" oil filters but have never seen any testing...

You can also buy WM AGM batteries on line & shipped to your home free. Just put an H7 850cca with 4 year replacement in my Silverado for $170 shipped to home.

Could be counterfeit plugs.

Yeah, check your mower too!

@Titan......can I assume you have the M Adaptive drive system? They take special fluids. Not like our standard 35i xDrive. I was never implying these fluids on this topic were good for M cars. They're a different bread.
