Re: Save money on your brake fluid, air filters and oil change by doing it yourself!

Our driving style is as follows: we are retired so avoid driving in the rain/snow; we rarely use brakes (regenerative braking is sufficient) so braking system doesn't heat up and cool ie "breath"; car is stored in a garage (ie out of the weather).

Re: Save money on your brake fluid, air filters and oil change by doing it yourself!

I have experimented with the gravity method, the two person brake pumping method and the vacuum pump method. All work ok. I prefer the two person method. We drive 20,000 to 30,000 km per year. A 3 year frequency is plenty for our style of driving. Bleeders seize after 3 years so are easily broken. W...

Re: 80m commute no charger at work; REX or no REX?

In 4 years of ownership I have forgotten to plug in a couple of times. If I didn't have the REx and this was my only car I would have been stuck.

Re: 80m commute no charger at work; REX or no REX?

How long are you planning to keep this vehicle? Once the battery degrades you won't have the same range. So you may want to consider REx if you are planning on keeping vehicle over long term.

Re: What octane rating is right for the REx: 89 or 91?

Likely nothing to do with octane rating. My understanding is that there are far more additives in premium gas compared to regular. Top tier gas also has more additives. Mid grade is simply a mix of the two grades. Fuel injectors keep cleaner with more additives. This is important for injectors that ...

Re: 12 Volt Auxiliary Battery East Penn Deka AUX18L

I have replaced many 12 volt batteries over past 50 years. This one was almost as difficult to replace as the one located in the passenger footwell of our smart car. Imho this battery replacement should only be tackled after watching online videos how to. No idea if replacing battery yourself will n...

Re: 12 Volt Auxiliary Battery East Penn Deka AUX18L

When dealer replaced our 1st battery in Toronto Canada we had no symptoms. Apparently they saw messages in car CBS history that informed them of defect. Had 2nd battery checked by dealer during 55 point inspection done at end of warranty. They said it was fine. Over the past year we have seen severa...

Bought battery from dealer. Installed it today. Didn't register it (don't believe this is necessary). 2015 i3 with REx with 81,000 km. 3rd battery. 2nd battery would be 3 years old in June. 1st battery replaced under warranty (defective). You guys have made me paranoid! Got battery about a month ago...
