Job location changed and I ran two quarts low all of a sudden *(over six months) when I began driving 30 minutes round-trip per day at speeds of 65-75 mph at 3k+rpm. I NEVER had a problem with oil consumption over same milage/time interval traveling surface streets to work -the Subie shop would have mentioned it, right?
I'm back to surface streets, new job location, same milage/time interval and have added 1/2 quart over past six months to keep it topped up.
Sure, NOW I check my oil at each fill up.
Sure, NOW I'm going to replace the PVC valve.
Sure, NOW I'm going to ask the Subie dealer, 30+ oil changes and 100,000 miles since new, why they have never mentioned PVC valve.
I have never believed in 3,000 mile oil changes. I peg it at 5,000.
When is the best time to check oil level? Stone cold? Fire hot? Luke warm? I get different readings between the notches/holes at different temps.
