good to hear so many happy with their 8.1 w22....i'm still scratching my head and wondering then what happened to our 8.1 w22 with the allison tranny. and this from a one-owner coach who supposedly was extremely conscientious about maintenance.
Easy, 8.1 Vorteck could not meet EPA standards so it was discontinued. I read where a new Workhorse engine is almost read for release. My 8.1 W22 does not use excusive oil and I have 66,000 miles on it. Pull a jeep liberty 4 time across country including Canadian rockys.
r0n.....:D
Actually after a long production of the 8.1L engine, GM decided to support the newer Duromax 6.2 engine for their truck line of vehicles.
The 6.2 could handle the same load and promised better fuel economy.
