Everything trending down still. Viscosity still well within 30w range even w the fuel dilution. Could Mobil 1 have added Magnesium?

Iron & Aluminum are up as are viscosity base and calcium phos zinc. Maybe due to the fuel dilution being down. Prob go 7,500 from here due to oxidation. Similar driving conditions, predominantly short trips and lots of idling, with the 600 mi trip thrown in on the OCI. Vehicle was plagued w...

I think this was 5w40 Euro, and I think it was about 3k mi. From an 87’ 325i w/ 115k mi that was sitting for 5-6 years, driven for under a year and sat for another 5 years. Last oil change was ~11-1/2 years ago

Specks of what appears to be aluminum in the filter - Napa Gold (WIX). Fuel dilution is up even though we took a 1k mi trip 2-3 days before the oil change, and got the most recent software update. aluminum, iron and silicon all about half of FF dump, copper at 1/4. Tech notes on add-pack must be...

few notes: 8,392 mi. OCI factory fill Edge 0w30? FWIW Sample was taken via amsoil oil sampler but the tube was reused. Tube had visible moisture, I had tried to clean with brake parts cleaner. Was mentioned to the lab. I think I had sent in a 0w40 VOA at the same time, so the warning about the...

Sorry, I’ve been meaning to post this for about a month. Put this in a 19’ Atlas 3.6 EA390 CDVC VR6. Cheers!

A little surprised by the TBN technical data sheet says 10.2. Didn't shake the bottle at all for what it's worth.

Looking for a low NOACK, under 6% preferably, MB 229.51 or 229.52 (low SAPS) oil in 30wt. Looking around, seems like the Redline 5w30 Euro is my best bet. See some amsoil w/ 3.6-4.5 % NOACK, but its not 229.51/.52, eg their Heavy-Duty Synthetic Diesel Oil in 10w30 & 15w40. Whats the sulfated ash...

Foreign debris & excessive crush, or oil starvation? Same story on all 8 cyl's, but the journals look fine. Bought from a guy w motor knock who bought at auction, and the title reveals it switched hands quite a few times in a short period, leading me to believe someone may have tried to replace...

Anyone have any concrete info on this oil? What group is the base, and whats the NOACK?

Quick newb question, searched and looked through owners manual. What is the factory specd first oil change for the 4.8l v8. Sorry and thanks. I know this is a debate issue, which is why I'm just asking for the factory spec.

This is my dads old work van, so the best i can do is what he has relayed to me..... Front reservoir, smaller of the two, keeps losing all fluid, no apparent leaks. Hard Pedal, not mushy. Doesn't go to the floor, and does not help to pump. No loss of fluid @ the rear. And it seems what braking...

Is there anyway to find out oil's individual sequence testing results???

Is there a specific viscosity for certian main and or rod clearences? Would HTHS be more important here? And would it be different for different bearings throughout?

How long does it take for internals to work harden? I know its going to be different for different metals etc, but I'm mainly curious about valvetrain. Is it a heating and cooling cycle thing or just friction? Is it something that happens during the 20 min break-in or does it take years?

I know, I know it's not new! I figured I'd have 10 people telling me this withen 10 minutes, settle down you oil nerds! I remember reading about it about a year ago, does anyone have any updates on it? Are any blenders employing it? Would it show up on an avg spectro analysis? How does it rack...

With a 1.6 rocker, P5249464 springs, and crane 753901 cam I calculate my lifter load to be 390.72# change that to 1.7 rocker and I get 415.14# HOWEVER I read a bit more and come up on this; "The actual load on the lifter foot is the sum of the static spring pressure, the frictional loading in...

Moly Is Back!!!! Emailed requesting 40*C Viscosity.

I tried to search but couldn't find anything in the past year. I went and picked up some RL at a local speedshop, and saw this Problend. Claims to reduce oil Temps up to 60 degrees, double valve spring life, and reduce bluing and galling. Sounds like it's loaded with FM's?

Could someone tell the HTHS minimums for each viscosity, and some oils that meet theminumum of the next highest grade. For ex I believe Fuchs Titan 0w20 meets the 30w min. Thanks in advance.
