High Mileage Oil in Phase II EJ25 SOHC

Charlton · 08-08-2012, 02:43 PM

Advanced Auto was running a special yesterday on 5 quarts and a free filter for $24.99.

I used the Castrol High Mileage 10w-30 in my 2002 Subaru Forester.

What oil are you folks using on high mileage vehicles? Did I make a good choice?

Oil is oil unless you buy expensive oil like mobil 1 or royal purple. Every oil has a different additive in it to help prolong the life of the oil due to the companies testing but all in all if they meet specs on the back of the bottle they r all the same. Change oil when every 3000 miles or 5k. Personally i know all oils break down before this amount of mileage due to the reason oil life is actually based on engine hrs not mileage.

I was going to split the difference and do every 4,000 mile intervals or 5 months.

I run Rotella T/5/6 depending on vehicle application. $13 a gallon for the basic stuff leaves more money to spend on a quality filter like Bosch or Purolator.

I was running the Rotella T in an EA82 Subi with 336k miles on the clock. No issues. Might save you some $$ later on.

I've been running Valvoline NextGen Maxlife high mileage 5w30 in my 01 Forester. I need to get an oil analysis to tell what is really going on.
