The (Amsoil ASL) oil in my 93 Suburban is over a year old, (more line 18 months) but only has about 2K miles on it because the vehicle gets such ________ mileage and I drive my Camry instead. Also has a Amsoil SDF filter. Any reason to change it anytime soon?
 
The Suburban stays outdoors, for the past 6 months or so on the lawn. For the past 2-3 months it did not move as I was getting up the energy to change the fuel pump. Which I have now.
 
You might want to think about putting an EAO oil filter on there. The media in a conventional filter will degrade due to exposure to the contaminents in used oil. This happens whether the engine is being used or not. The synthetic media in the EAO oil filter is not affected by fuel and other volatile hydrocarbons.

Whatever the oil, what would concern me would be water condensation inside the engine, given that it's parked outside. I'd try to take it on a 30 mile drive once a month.
 
I would think with the short mileage, long time frame and fuel swilling V8 that oil has had it's hands full. If it were my truck, I would be more comfortable spending the $40 to change it if I were looking to keep it for a while.
 
Did I mention it has a 46 gallon gas tank? How how much is it to fill this baby?

Tooslick - isn't the Amsoil SDF also a synthetic media? Are you suggesting to just replace the current SDC with a Ea filter and not change the oil?
 
Pablo - it was pretty close to dry as I just dropped the fuel tank to replace the fuel pump. Every gallon in the tank is 8 pounds I would have to lift up getting the tank back in place.
 
Donald,

Based on my early testing of the EAO filters - yes.

The SDF is a synthetic blend filter and does contain some celluose,along with glass and polyester fibers.

Be sure to use some form of a fuel stabilizer if the Suburban is used that infrequently. I agree with the suggestion to run this truck for 30 minutes at regular intervals. Condensation will build up in the motor, transmission and differentials any where the fluid isn't sitting. Running it every so often should keep things nice and clean.
 
I have been told if you follow a good safety procedure as in tirechains or locking straps around the back tires secured a stable point. That leaving it idle in D puts a good amount of load on the engine then just idling. Thats only if you can't drive it though for whatever reason. Driving it would obviously be much better.
 
Part of the low mileage reason was a broken fuel pump that I had not gotten around to fixing. I finally had to fix it as the broken pump had a 1 yr warranty and needed to get a replacement under warranty.
