It's odd, and I noted earlier/and in a different thread, somehow, 75mph has weirdly been a "sweet spot" where I get better gas mileage going 75 than I have at 65 and 70. Obviously there are a lot of factors involved, but it's very strange. My hypothesis is that 75mph (~2700-2900rpm or so?)...

0.2 tenths off my best mpg ever this past drive. all highway, on 0w20 amsoil, at speeds averaging around 72mph.

aaaanyway, on topic - in general i do agree with this post. seems like different cars have different "sweet spots" as far as the engine work/efficiency vs speed/wind resistance goes. for the 4 speed automatic corolla, it too seems to get the best mpg around 75mph - just wanted to see if anyone...

Noticed on more than one occasion. I definitely agree it is odd. While it does need more fuel, it runs hotter and produces more torque, which requires less "throttle" (I use cruise control the whole way). I'll test again in the summer when the fuel is normal and more stable.

^ I have auto. Right now I'm averaging around 31 mpg or so. I was just commenting on the fact that it seems like I get much better mpg cruising at 75mph than I do at 60-65mph. I wonder if anyone else has found the same. Always do Shell or BP, and am using fuelly to keep track of mpg with the...

I usually do notice a pickup of 1 or 2mpg when I switch to Amsoil - can't say I've noticed much with the Corolla though. The trans fluid is on my list of things to do once the weather gets nice again. Weirdly, I've noticed that at 75mph, the car tends to do significantly better in MPG. I can...

has anyone noticed an increase in mpg in the automatic corolla going around 75mph? this may be questionable to some, but engine are more efficient the hotter they get - i think cruising close to 3k rpm at 75mph is definitely getting higher mileage than puttering around 2500rpm at 65mph

long time bump. is there any way to play media from phone/ipod through the car's speakers?

car running well with SSO 0w20 in it now! Unfortunately, keeping track of any mpg is about moot, since we just switched to winter gas here.

i believe these cars were back-spec'ed to run 0w20 by Toyota. regardless, i doubt it'll make a difference in the winter. http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2430478 here's the actual TSB: http://www.matrixowners.com/tsb/TS-EG018-06.pdf...

way late response. sorry guys. i realize there are differences with pumps etc yada yada - this should average out over time and fillups. just as easily as the clicker stops early it'll stop late etc etc. over a hundred fill ups, the average should be the appropriate mpg. I think in my case, my...

Thanks. I did look into it and the w20 oil is backdated for at least the 03-08 corolla, and most likely that's what it's been fed. I have no hesitation with running 0w20 since the car is just daily driven to and from work for a relatively short trip (10-15m) so a lighter weight oil will probably...

i did NOT know the oe oil that was used was 0w20, that will probably solve it. i know the bulbs will probably burn out faster - replacing them more often is not a problem with me in exchange for the increase in output - and they definitely don't burn out as quickly as the other "white" halogen...

update-ish: - after a few more days, i am definitely enjoying the increased and whiter output of these headlight bulbs. i will probably continue to use and use on any car i get in the future that may not come with halogens - i've taken a few highway trips now, and oddly enough, my best tank...

after driving it around a little i can definitely say the light is a little bluer than i'd like - i doubt this will go away, at least with most HIDs the light gets bluer as time goes on, but overall it is a huge improvement to the old lights - at least 30% great light output again, it passes...

Before and After: Crystal Vision Ultra - 09/12/2013 Just a quick before after snap of the crystal vision ultra: not at the exact same spot but definitely a marginal improvement, which is exactly what I was expecting. A lot of the "bad" reviews about this bulb were from people expecting this...

not a bad idea - i try to do the same but i haven't had this car for very long. it may end up being that way just because i dont think the transmission filter i ordered is going to arrive on time. the effects of going to sso 0w30 are obvious though, even my girlfriend can tell lol

gotcha - I did order the atf, hoping to tackle it this weekend, have a trip coming up next week and would like to get a read on how it feels and if there's an improvement in shifting and efficiency. also need to change the plugs which I suspect will have a big impact on efficiency.. I think...

lol jeez i thought i was the biggest amsoil fanboy i knew of.. i did get ATF, but no one, even some of the more extreme amsoil dealers i know, will tell you that using OE fluid will ruin your transmission..

on a side note, this forums not emailing me instant notifications for subscribed threads like i requested.. need to look into that actually while we're at it - recommendations for spark plugs? looks like denso iridium 3324 is the OEM part? Hopefully it comes pre-gapped. I talked to the dealer...
