Well, I say it's always good to rev her up to 4000 at least once per day. A retired landrover underwriter told me to do this. He says too many of these engines are babied and they are meant to run. He said they are built to handle tough conditions as long as they are well maintained. I have to agree with him. The rougher - as in occasionally putting the hammer down, offroading, pulling ****, etc... - she just seems to run better. I babied her for a while since gas prices are so high but she started to run a little rough. So back to driving like a bat out of hell...and now she runs smooth.... and to top it off... I get the same gas mileage as I did when I babied her! Yippeee! :buttrock:
