Another fuel saver, i hope...
 

Hello everybody!

I'm from Portugal, i'm a mechanical engineer and i drive a opel astra 1.3 cdti caravan (2006). I started keeping a record on an excel spreadsheet of my mpg about 10 years ago. So far i haven't made any mods to the car (except for a 0.4 bar increase in tire pressure). I'm planning on putting rear wheels deflectors and maybe a grill block one of this days. I have a scangauge on my other car (opel corsa 1.3 cdti (2005) because it didn't had a board computer.

My best regards

Paulo

Welcome to ecomodder :)

The grille block will be more effective.


If you block it from the inside, hardly anyone will see it.
Keep an eye on the coolant temperature with a grille block - you could swap over the ScanGauge for a while. The built in temperature gauge is very crude in most cars.

My opel astra doesn't even have that crude built in temperature gauge. I don't want to swap the scangauge because it took me some time to conceal the cable and i don't want to do it again. I'm thinking that if i can find some adequate software, maybe i'll buy a cheap OBD to usb cable online and use a small netbook that i have available. Thank's for the tips.

astra74 welcome to the forum. I'm interested in seeing your years of data compared with your upcoming mods. I bet you have a solid baseline on that beast to compare with. As long as your driving habits don't change in addition the mods should be a great comparison. I'll keep an eye out for your post.
