just as the thread says

 

My sister and I both have 95 Z28 A4's.

97K on mine and 105K on hers.

Mobil one 5w-30 in winter

Mobile One 10W-30 in summer

Neither car consumes more than .5QT in 3000 miles. No leaks.

Always use Delco filter.

 

well, i have 73k and i use mobil 1. Its the best.

 

valvoline max-life.

 

i have been using castrol syntec 5w-50 since i bough the car with 80,000 on the clock. Now i have 115,000 and no problems at all even in New York when the weather gets below freezing.

 

Mobil 1 pure synthetic here

 

Just switched to valvoline 10-30 full synthetic
89,000 on the clock

 

90,000 miles and I use 5w30 Royal purple in the winter and going to use 10w30 in the summer and I also use K&N oil filters.

 

i use 5w-30 valvoline durablend all year around......little bit of leak, no biggie.......and i use pepboys oil filter, gonna switch to kragen's one soon

 

Valvoline VR1 racing oil, 20-50 weight got 156000 on the odometer.

 

107k, using valvoline max-life 10w-30. No complaints with it, it may help a bit with the leaks.

Got about 94,000 use mobil 1 5w30 with no problems.

 

Over 166,000 miles...
Mobil 1 5-30 ever since I've owned it, and I don't know if it burns oil, or if it's the rear main seal leak, I lose about 1/4-1/2 quart every 4000 miles. No white smoke, so that tells me that my engine is running pretty good.

 

Castrol 10-30 Syntec.... I do have leaks at the rear seal and at the cam seal. Not much, but enough for me to wipe down the mist residue at each change.

 

15W50 Mobil 1. I've got 99,000 miles on my SS. It has around 450 n/a hp. It's had this much hp for about the last 85k miles so that ain't too bad
