Engine Oil Question

[UH1CW2]

I have been using Shell 100W for over 15 years and it seems to have performed well. However, several people on the field are telling me that the Phillips 66 Victory 100AW is a better oil. Does anyone have some experience using the Phillip 100 AW oil? If so I would like to get some feedback. I ask because I am a bit old school and just don't change that easy. However, if Phillips 66 is a better product I am open to using it.

If you know of a better oil I would like to hear about that as well.

Thanks Guys

Let the oil war begin. Popcorn going into the popper. :-)

I always use Aeroshell 100 Plus, which includes the antiwear additive LW-16702 same as the Victory, which oil is better.. who knows, but I'll stick with the Aeroshell till someone proves otherwise.

I just use used diesel oil from my tractor, seems to work fine.

I use neither of the two oils you are trying to determine which is better.

Both meet the same spec.

IMHO, the one that can be obtain or delivered local at the lower price is the better one in my book. If they are both the same price, which seller do I like better?

They say the cheapest thing about flying is the pilot. Yes I fly and I am a pilot. If the shoe fits, I will wear it.

i use aviation oil, i fly a lot and change my oil a lot. i have a lot of oil stacked up ready to go. my engines have gone way past tbo with high compressions. diesel oil? not sure about that one. add some mmo once in a while, i do.

This is what the tech expert at Aerosport Power recommended. He advised to stay away from the multi viscosity oils and stick with 100 weight in summer and 80 weight in the cold months.

I go with what Lycoming recommends. They have lots of data and financial skin in the game. No brand names called out just oil spec.

This is pretty much what mike bush says... I have no technical knowledge on the subject but I decided to believe what he said about oil. If you have an hour of free time you could listen to his webinar. I think he says " 15W50 is his least favorite oil...

I just finished Mike's "Engines" book. I thought it was good.

I think he recommends straight 100 for most of the time and Phillips 20w-50 for cold winter months in northern climates.

He also likes CamGuard.
