The packs provide all cooling and heating as well as cabin pressurization. Even when it’s cold outside. In this case you’re off the gate on engine power. The engine bleed air systems are supplying the packs. The fumes could be from many things engines, pneumatic systems, packs themselves, or...

Most modern airliners have 2 air conditioning packs. They’re usually run with engine bleed air. 1 pack per engine or both packs on a single engine if needed. Also the A/C packs can be run with APU bleed air. The only jet with electric packs is the 787 along with electric engine start. The 787...

Looks like a great report! Cutting down the idle warming time in half should help with the fuel dilution. 5k OCI looks achievable.

Very good feedback on this thread. It's nice to start seeing more reports on newer D.I 2.5L boxer engines. I downgraded and placed an order for Amsoil OE 0W-20. Planning on just changing oil every 3-3.5k miles Spring/ Fall schedule. My next UOA I'll be using a Amsoil filter already on hand...

Looking at this report the oil viscosity is till within effect. Hardly effected at all with amsoil signature.

Our Subaru is kept in a heated garage. It's exposed to the cold weather during the day at work. I can't imagine how much dilution if it wasn't garage kept.

Typically 140-180 F* depending on how frigid the weather is.

I try to have a nice highway run once a week to burn all the contaminates.

Here’s my results for the Subaru Outback Limited 2.5L Direct Injection NA engine. It had roughly 4800-4900 miles at sampling. Amsoil Signature 0w-20/ Wix filter. Oil was changed last September and sampled this March. This vehicle is used for roughly 4 miles daily commute round trip in Minnesota...

The fuel dilution actually was user error. I would idle the engine 15 minutes every time in the Minnesota winter sub freezing temps. Which I believe contributed to it. I’ve changed my habits since then. I have relocated to MN and the new annual mileage should be around 7k miles give or take 1k...

Hi everyone, I recently changed my oil on my 2021 Jeep Gladiator 3.6. Current oil run was 9.5k miles. Vehicle has 12k total lifetime. It has a 5qt sump and burned roughly 0.8 to 1.0 Quarts during this interval. So roughly 0.5 Quarts every 5k is the current average. I’m running Amsoil Signature...

I only did the engine flush to prep for the new amsoil and clean anything out. I don't plan to flush again since I'm planning on sticking with signaure oil.

It’s a good practice to get most of the old oil out. Considering it had 2700k at the time. It’s not a bad idea try to get as much break in material/ assembly The tech explained to me that it will take 2-3 oil changes to get all the old oil and flush out. I’m guessing the small mixing of such...

It’s a good practice to get most of the old oil out. Considering it had 2700k at the time. It’s not a bad idea try to get as much break in material/ assembly grease.

Thanks for the clarification on the engine fuel injection. Yeah I’m definitely reducing the idling from now on in the winter.
