With the cheapest oils, make sure to change them frequently. Use a strong light to look inside the valve cover to check for sludge and varnish build up. You'll want to get rid of that stuff.
Yes, you can post photos.
You are very wise to use distilled water with the antifreeze. Hats off to you! As I'm sure you know, tap water has all sorts of things in it that are not intended to be inside the cooling system of our engines and they can have negative affects.
That is outstanding fuel economy! :thumbsup::yes: Do you do anything special to reach those high mpg's?
Yes, this is a civil group and there are a lot of really nice and knowledgeable people here. The Corolla Forum is very unusual as forums go, as here you can talk about anything you wish without fear as long as it isn't personally attacking another member, using vulgar/profane language or promoting an illegal activity. If you want to talk about God, religion, politics, or what have you, that's fine as long as it's civil. If someone else doesn't want to read that, as with anything in life then they have the wonderful personal option of not reading it or participating. Simple as that. :thumbsup: Here freedom rules, not dictatorial, heavy-handed, pushy, "You can't say this, or you can't say that". This has resulted in a forum where everyone gets along pretty well and as a consequence, the Corolla Forum is growing by leaps and bounds. :thumbsup:
In the Corolla Forum you will find a plethora of topics of discussion, all manner of technical videos on maintenance and repair, as well as various entertaining videos in the, "Off Topic", forum. We even now have a, "Song of the Day Thread", where members can share their favorite songs with other members. In the Corolla Forums area there's a large amount of information on the various years of Corolla's from EPA fuel economy ratings, recall information, typical complaints/problems with certain years and models, etc. So feel free to jump right in and have fun in the Corolla Forum!
