Re: The difference between nice-on and fas
I need to get another set of eyes and a stopwatch. I just have trouble believing that I wouldn't get slightly better FE in N than in D. My crude eyeballing and counting seems to indicate that D and N are the same in the 25-40 mph range.
I would certainly do better if I shut off , but it is just too much for my 57 yo brain to manage safely.On my 1st rolling shut down I shut down in D ; needless to say I didn't glide very far in D with the motor off. With more practice I could manage it , but I have to pay more attention to my driving (beside engine is old,so is trans-206,000 miles 11 years). Another problem - already mentioned - is that big motors older vehicles (5.7 V-8) seem to take longer to warm up . I get no benefit from shutting off at a 30 second stop until it is fully warm- maybe 5 miles in the summer.
Shutting off in the glide saves plenty of fuel, but too tricky for me. I have my limitations.
