So reviving an old thread. Oil consumption has held steady around a quart every 500 miles. Tried the Rotella T6 oil, no difference. I do have an oil pan gasket leak but it is drops at a time (I have a plastic mat on my garage floor under the engine and it is literally drops every day).
However I recently took a road trip to golf at Bandon Dunes and drove 500 miles RT. I made sure the oil was full on the dipstick when i left. I checked the oil when I arrived at Bandon, no drop in oil. And checked again when I got home, no change. Apparently I burned no oil for a 500 mi RT when I typically go through a quart over that distance.
I did have the car on cruise control most of the way and was averaging 80mph.
Why did I burn zero oil on this trip? It is the constant RPM? Just curious why this would be the case. I haven't driven much since I have been back home, so can't tell if the normal oil will return. Just very odd to have no oil consumption. Any advice would be appreciated if someone had a similar experience.
