Just got my first oil report back on Rocky since moving the car from BMW 10w60 to Red Line 5w50. Seeing high silicon levels which can either be due to an additive in the Red Line oil or dirt passing the filter. I am using a Pipercross foam filter and wondering if anyone else has run into high silicon levels, and whether they are running a foam air filter or using Red Line. Or in my case both. I perused the thread and didn't see anything to guide me. Have a question into Red Line and sometimes they do respond.

Pipercross has some guidance for track use only on some of their filter products but my understanding is it doesn't apply to the one I've got installed.

Thanks, all.

The car takes 10w60

Why are you running 5w50

Redline 5w50 is equal to the BMW and Castrol 10w60 spec products (RL 10w60 is considered too heavy). Red Line's synthetic oils are ester based which is considered a step up in lubrication and engine protection from the Mobil 1 / liquid moly / castrol / BMW synthetic oils, especially in high revving engine applications. There's a nice little thread somewhere from one of the S65/S85 aftermarket engine builders showing a wear comparison and he advocates for RL 5w50. Here, the metal counts show the 5w50 is performing exceptionally well.

I've got a couple questions in to Pipercross and Red Line.

Update:

Spoke with Pipercross and they confirmed the px1828 is designed for daily driving and that they do run into counterfeit parts on the market. I had purchased mine from an eBay reseller and it's a risk.

Spoke with Red Line and they confirmed that the expected value of silicon in 5w50 is 20 for the additives they use and that because they don't disperse a sample may measure higher. Similar narrative from Blackstone.

I have never liked the design of the air filter and how it essentially presses against the plastic adapter on the engine side of the intake and is sealed and held into place by a spring tension on the edge of the airbox. I decided that 70ish on the silicon was a little too high for my comfort (meaning I felt the risk I was pulling in unfiltered air and dirt was too high ) and purchased a K&N filter as an alternative.

Pulled the airbox and filter mechanism apart this morning and put my hand inside the intake elbow: Grit. No bueno. Cleaned that out and installed the new filter. Was pleased to see the K&N has a different design and snaps into the plastic adapter with a rubbery seal and I think significantly reduces the chance for unfiltered air to get sucked into the intake. Now I wonder if this is the OEM design. Glad I follow my oil reports, this condition could have gone on a lot longer.

Pictures show the dirty towel from the intake, how the Pipercross as purchased simply presses against the intake adapter, and how the K&N fits snugly into the adapter well enough to defy gravity and then some.

None of ghat is true except that RL 10W60 is too heavy.
Final product is what matters, and that is achieved by using various base stocks. RL is ester based, but Mobil1 has a lot of ester in their FS and ESP oils. Problem is starting oxidation of ester oils and unbalanced additive package of RL that somehow always has high silicon, which is not good for street driven cars.

As for wear, people have to understand that UOA is not designed to measure that. It can show spike in metals to point to an issue (rod bearings) but wear can only be determined by tearing down engine. All those ball tests etc. are just bunch if nonsense. I don't remember any from my days of oil development and testing.

Keep us posted on the outcome of this one.
Hey there, sorry I didn't provide an update sooner ( I haven't been active on here much since the accident).

My car was indeed deemed a total loss. Thankfully I really didn't lose too much money. Just a bit lost on my mods, X pipe, tune, etc. Since the market was up at the time, that helped the payout.

I did end up getting into another V8. Though not a E9X; or a Bimmer.

Ok, Boomer…. You almost hit the trifecta there. I'm not really interested in a debate on oil viscosity, oil brands, nor the value of oil analysis - but thank you for posting. If you need me, I'll be on another thread debating the true cause of rod bearing failures and which is the very best exhaust setup.

He's right, though.

I am not sure where you going to be, but that doesn't change facts.

Nice job finding and eliminating the source of all that dirt getting into your engine. I always hated foam filters for any kind of street use for this reason. I've seen way worse levels of junk getting through foam filters even when they had zero leaks around them, the typical JDM brand ones are the worst.
