These figures are from an Audi 2.8 V6 12 valve engine. The engine consumes a little less than 0.5 qts per 1k miles at this time.
Compression of new engine: 9-14 bar (130-203 psi)
Minimum compression: 7.5 bar (108 psi)
At 130,000 miles, the results seem very typical for this particular engine:
Compression (psi):
Cyl 1: 200
Cyl 2: 210
Cyl 3: 205
Cyl 4: 200
Cyl 5: 195
Cyl 6: 200
0% Leakdown on all cylinders
How would you read these figures and the compression variances? Do they indicate (some) sticky rings?
Considering the compression numbers and leakdown test result, how do you explain the oil consumption?
