    As OR17 posted........"Axshole wrap happens more with lots of stop and go traffic. Complete stops pause and then a bump."..........Normal for our Tacos.

    I’m almost used to it now. It’s strange mine doesn’t do it every time I stop though. Not sure why

    It is odd. Is that the motor or something else. The 3rd gens have some odd little things they do. But I’ve got used to the way they are. I guess not as noticeable as they used to be

    It won’t. It happens more with abrupt stops. If you ease into the stop it won’t usually do it.

    It’s normal but you could say something. The more people that complain about it the more likely toyota will put out a TSB to fix it.

    The 2GR-FSE is tuned for 87 to 91 octane. At 87 octane its 304 HP and 278 lb/ft at 91 octane it makes 314 HP and 280 lb/ft.

    The 2nd gen 1GR-FE on 87 octane is 236 HP and 266 lb/ft on 91 octane it goes to 240 HP and 278 lb/ft.

    I'm pretty sure every Toyota VVT-i engine does this. I think it takes the engine a little bit to adjust so the first tank might lower mpg.

    It shows it on the engine page on Wikipedia and I've read about it on different forums. Also Toyota test engines at 87 octane but Lexus they test at 91 octane same engine different power numbers.

    I suspect manufacturers could make higher power and more efficient engines with higher octane and higher compression ratios. People buying Toyotas might be peeved if they said they had to run 91 vs the average Lexus customer. So makes sense to rate the engines by what the customer will most likely run it on.

    Yes but things usually get corrected fairly quickly. Also, it has said those figures for many years.

    It may not be the best idea to assume something on wiki is correct on first glance but if you look back and it always stays the same its probably right. Also if you find the information on other sites and discussions. There is a surprising amount of people correcting wiki.
    You can also check the source pages where the info came from (not always) and the history of edits.

    You can do some research its talked about for multiple engine models and if you look at Lexus papers for hp it will usually say tested with 91 and then check Toyota it will be a slightly lower power number tested at 87.

    Manufacturers are actually pushing for single grade 95 and get rid of everything else.
