Car is usually driven 55-65mph to commute. No major hills, wind, etc. I'd consider it a super easy on oil commute. And often push past the 6k change interval.
Recently road tripped about 2k miles each way. Uphill, downhill, mountains, into strong Midwest winds, all with cruise set at 80+mph at times. Is this severe? I added 2 quarts of oil, I'm assuming due to the engine load and higher than typical rpms (4k+ uphill).
Would you change at 6k or let it go until 7-7.5k?
Looking forward to contradicting views already!
