It averages about the same as before since the W58 has a shorter 5th gear than the 4th gear on the auto. If you put a diff lower than 3.9x then you should see fuel economy.... but 23-24 is probably more attainable.
Really? I really don't care what you call bullisht on, A properly tuned up 5 speed sc300 on 100% highway driving will teater on 30mpg mark as I have done it many times.
Some pos clapped out sc300 5 spd with a wannabe Ken Block drifter behind the wheel will not yield these results so if the shoe fits....
a 98 with a 3.27 diff averages 23-25mpg highway, no way your 3.92 diff averages the same and without variable valve timing. also no way a sc300 will ever get 30mpg highway.
Hmmm I get 23-24 highway now at 70mph, I was hoping for something better as my sc300 5spd has gotten about 30mpg all highway before.
exactly why i want to swap a manual in my car 22mpgs aint bad for my sc3 especially for its age but i want more! props to the v8 guys for getting in the 20s though thats not bad at all for a heavy v8 powered car

I said teaters on 30 mpg so to be exact 28-29 5 speed non vvti 95 sc300 with 70mph cruise speed 100% highway and yea unless you have the exact same car with the same driving conditions your comment is baseless.
I was talking about the sc300 not sc400 when I said this again NOT the sc400 This thread is getting confusing because of all the pointless bickering as the question was me wondering what the 5spd sc400 guys were seeing for mpg.
