Met an old timer courier today that I have seen over the years but never talked with. Today I noticed his truck was re-painted and oh, looked so fine for an old truck... I asked him his miles, he said 741K. I asked when he rebuilt the engine, and he said right at 600K. I asked why, he said because it would not pass inspection. I asked him why, he said because it blew too much smoke. I asked How MUCH, he said between 1/4 -1 Quart a day (tank) I asked him the average, he said usually 1 quart to 3/4 quart a day unless he didn't get on the freeway. I asked him When this started he siad in the high 300K to low 400K and just got worse until it was burning what it did. I asked him what oil he used, and he said CASTROL 20w-50 since new, and on the rebuilt too, before the 20-50 he'd use a straight 50 in the summer and a 20 or 30 in the winter. He said his secret besides the oil was to not ever have a leak and to always rebuild anything like starter or alt, etc. and stick with the original motor. This is his second truck that he's done like this. We talked about the rear end, never changing the fluid with 741K original miles, but the tranny he rebuilt when the engine was done at 600K.
I listened to his motor with 141K on it and it sounded like new, as he pulled away, he said to me, to just pick ONE oil that you like and one method and stick to it and not to change. HUMMMM.
