The 2011-on FB engine is built with close tolerances to run on lower viscosity oil than the pre-2011 EJ engines, with the low viscosity oil still maintaining shear strength by being synthetic.
 
Using such low viscosity 0W-20 oil in the older engines would likely result in high oil consumption. Conversely, using 5W-30 oil in the FB engine would likely result in poorer lubrication and mileage.

I am interested in purchasing a used 2001 Subaru Forest (automatic) w/168K miles and apprears to be well maintained (will verify with carfax). I do know that the car was recalled by Subaru and had Engine Cooling Conditioner added given the concern for the HG problems.
 
My question is, to be throughly covered, is it advantageous to flush the coolant and replenish with the K Seal.
 
Any thoughts or comments.

Subaru's coolant conditioner is supposed to be added to a coolant change every 30,000 miles. It is the only thing that Subaru approves. But if you already have an active leak, you may as well add the strongest goop.

Now I am strongly considering purchasing a 2003 Subaru Outback Legacy Wagon L (automatic V4 2.5L) with 139K. I don't think it has a HG concern/problem, but will have it verified in the next cpl of days with my mechanic (didn't the 2003 have a re-design on the HG?).
 
If one wants to be proactive (not re-active) and do everything possible to deter problems with the HG, what would be the best additive to the cooling system (eg, Subaru Engine Cooling conditioner, Blue Devil, Red Line, Purple Ice)?
 
Appreciate informed opinions.
 
thanks

Proactive - Subaru (Holt's Radweld) conditioner. Subaru evidently believes it won't compromise cooling.

Reactive - Anything else. Nothing to lose.
