My 87 GN has had an oil leak for awhile now, I usually have drops of oil on the ground near the back of the engine (rear main seal changed), it is probably the intake manifold or rocker cover. Anyway, I stored it for the winter with fossil oil and drove it for a little while with the fossil oil including some high boost "set-up" runs. No oil leaked.
Got the oil changed back to Mobil 1 synthetic 10W-30 and the oil leak came back with some lower boost runs.
Is this just coincidence??
