silverado ss with a k+n and many mods m1 5w30

[EvanD]

I got it in the mail let me post the highlights. They are completely boring.
3,500 miles in severe abuse mode used in extreme dust and towing a 5k boat.
The mods are extensive including K+N, increased timing, full exhaust,stall converter
I guess the oiled filter works as silicon was 7 the same as the averages
all reading within averages the sample was perfect.
The only difference was fuel 5w/30 held it visc, no fuel or water,Low insolubles on my fram filter
tbn=4.2

Can you link or include the UOA?

 

[Coogles]

Extensive mods = bolt-ons?

Extensive mods would be cam/heads/power adder.

 

[saberz]

Mods are mods, they all benefit(for the most part) the vehicle.

Where's the UOA?

 

[EvanD]

I have heads and ratio rockers and run a wet shot on occasion. I am considering a magna charger however daily reliability is my biggest concern at the moment.

Looks really good - could have done about 6-7k in this service.

I'm impressed with the visc. retention - usually, M1 5w30 shears to about 9.3-9.7....here it is still well above 10.

 

[saberz]

Only 3.5k miles on it so the retention is well in check. The oil looks to be in good standing.

The 2 UOA's I had done with M1 5w30 with similar mileage on similar engines also had kin visc's at 100C above 10 (10.1 and 10.4)

Looks great.

You can't have a K&N with Si readings like that. Aren't K&Ns "instant engine death"? I guess it's OK to keep mine in then.

Very good report. You could run it longer, lots longer.

Is it a straight K&N, or are you running the foam sock? The sock really makes a difference in filtering ability without compromising airflow.
