uh...that's tough to say.
I got 269K on my engine with no problems...no leaks or oil burning.
Joe had 129K on this LT1 and when he peered into the cylinders it still had the honing on the walls...
So, when does an engine wear? It starts the minute the key is turned...but with frequent oil changes and proper mantainence wear can be kept to a minimum.

Change the oil every 3K, use appropriate octane levels (nothin but '93 for my baby), change other fluids accordingly, don't drive it into a ditch or bus stop, and regular maintenance = forever theoretically.
But I would say 150K seems do be the dooms marker if anything for most cars even some can go 300K +. My opinion.

I have seen 150 and 80 k mile LT1's torn down, and, yes, you can still see the cylinder honing marks-
Between tighter manufacturing tolerances, and improved lubricants, there is no reason these engines won't go a long time- Taxi companies were typically putting over 300,000 miles on the Caprices- In the northeadt, the body will rust off before the powertrian fails-
Keep the RPM's reasonable, change the oil and filters, and keep them tunes so they running smoothly- fix problems when they are small, for example, easier to have your tires balanced rather than and replacing wheel bearings- same goes with plugs, wires, etc-2001 Z28 A4 - 160 deg t-stat, 3.42 gears, WS6 sway bars, rear springs and shocks, UMI SFC's, Torque Arm and STB, leather Firebird seats, Borla, SLP Y-pipe and lid, ZO6 cam and springs - 332 RWHP and 346 RWTQ, not bad for 'almost stock' - work in progress

I've taken apart others at the same mileage and many were already toast, they used cheap oil and changes were not as frequent. Draw you own conclusion.

I had about 134k on my LT1 when I sold it. I had some accessories replaced...water pump, optispark rebuild, etc.. The tansmission needed a rebuild as well.
The engine itself was great! It was running strong with no problems whatsoever. I should've kept the car and not sold it...ah well.Joe K.

Should 10W30 be used instead of 5W30? I've been using 5W30 for a while and everytime I look online at oil sites, it seems to suggest 10W30 is the recommended grade for the ol' 3800. Does it matter either way?1997 Pontiac Grand Am, 216k+ miles and still moving fast

Heavier weight oil *may* slightly decrease your mileage, harder to move around. It is sometimes used as a bandaid if you have wear in the engine, to hold a little higher oil pressure.
If you have adequate pressure, particularly at idle, with the 5W oil, use it- you will get like a half a percent better mileage- if you need higher pressure, you can use the 10W- Not sure what the General specs for the 3.4 motor-2001 Z28 A4 - 160 deg t-stat, 3.42 gears, WS6 sway bars, rear springs and shocks, UMI SFC's, Torque Arm and STB, leather Firebird seats, Borla, SLP Y-pipe and lid, ZO6 cam and springs - 332 RWHP and 346 RWTQ, not bad for 'almost stock' - work in progress
