1.8 VTEC Bad Economy?
Hi all Civinfo members! Hope you can help me...
I'm a long time viewer of the forum but never posted before! Proud owner of a 61' reg 1.8 Type S GT on 56k miles. Had it for nearly two years and I love it! Handles very well, it's comfy for long business miles up and down the motorway and that n/a engine (whilst no Type R) is a peach!
However, I have a query regarding MPG... (and before you ask I have checked out the many threads on here!)
Typical driving is 10 mile commute each way from work. 50% motorway, 50% city/stop start.
Can't seem to get above 33mpg even driving like a saint, normally it is around the 31mpg mark (which probably works out about 28mpg real). On a long run, 60 mph returns an indicated 45mpg, 70 returns 40mpg, 80 returns 35mpg and a recent long motorway run at 85mph got 40mpg? Go figure...
Fellow 1.8 drivers - is this normal???
Got a couple of theories why it might be down - maybe you could shed some light onto these
- Runs on Honda 18" Rims. Bigger rims equals ***** mpg?
- Spark plugs never been replaced, on the assumption these are long life and don't need to be replaced until 75k.
Any help would be much appreciated!
