I'll toss this out to the lists for information and discussion. I just returned from a 3,000 mile, 27 day excursion from the Seattle area to Hollister and back. I'm driving a '90 Westy. I was traveling with another Westy, an '87. Both running stock 2.1L WBX, both automatics. The '87 is running 16" wheels, I'm running stock 14" alloys and 185R14 Agilis 61's. When we ran ourselves over a weigh station, I was about 300 lbs heavier than the '87 (I'm a pack rat) and in addition I'm running with a Bagawest carrier, sticks up better than a foot above the luggage rack. The '87 is carrying 'stuff' in the luggage rack, tied down. When these two vehicles ran together for about 10 days last fall, the '87 frequently used from a tenth to a half a gallon less gas than my '90 at fill ups. (didn't have the Bagawest at that time). On this trip, after getting an injector problem fixed a couple of days into the tip, my '90 consistently used from a tenth to half a gallon LESS than the '87! And this was not flat out highway driving, it was a lot of up and down, twisty stuff, Highway 101/1 along the Oregon and California coast, out and back. I had had a set of rebuilt injectors installed just before the trip. One went bad in about 100 miles and was replaced with a used injector. I'll let the list speculate on why the difference between the two vehicles performance, and also speculate (or just take note) that the performance of the two was so close. Waiting for comments…… |
