Ive noticed a sudden drop in mileage in my spfi ea82 wagon. From as low as 6.7L/100km up to as high as 9L/100 km.

Just did timing belts.

Switched 20-50 oil to 5-30 for the cold weather.

Can't figure it out. Any thoughts or suggestions?

Sorry to be brief. I just typed out a long post but by iPhone lost it and this is my second kick at this cat.

Thx for the help.

Aloha!

Winter-blend gasoline? Seems like too big of a change for just that though...

Is this directly related to doing hte timing belts, or did the car run the same, but all of a sudden lost mpg's?

Thx for the replies.

I'm filling up at the same pump as always. So I don't think it would be a change in the fuel.

I also changed the thermostat to a 192F unit. Can't see that making a big difference though. I think I'll need to change the water pump. But that doesn't make sense either.

I wonder if the timing belts are too tight . Maybe that would be a possible cause. Although I can't see that being the problem.

May want to check whether your wheels are dragging.

The fuel could change whenever your filling station gets their tanks refilled. So even at the same station at the same pump, you could be getting different gas than the last time you were there.

Maybe a tooth off on timing ....

Well the wheel dragging idea may hold some water.

Today on the drive home I heard the tell tale sounds of a bad wheelbearing.

I'm not gonna be driving it to work tomorrow.

Maybe Its the answer to my mystery.

Thx
