When receiving my rolla back from toyota the other week i noticed the box felt slightly smoother and cleaner.

I immediatly called the dealer and asked what they ahd done. To my shock he said "We didnt do anything!?" I wasa bit miffed when he said this and asked him why the car felt better.

Anyway I slept on it and then it came to me. The 'ONLY' thing (if he is true to his word) that was different........was the fuel! As the dealership is directly across the road from a Shell (Optimax) and I use BP (Ulitmate)

So over the past couple of weeks I have been using Shell instead of BP........and low and behold the box has shown some signs of improvement. Now this is by NO MEANS a fix and be all and end all.

But I would be intrested to see if anyone else here with similar issues to myself, and is running BP Ultimate to switch to Optimax for a couple of weeks (at least 2-3 tank fulls) and let me know what you think. (have you tried this yet Bill???)

I raved on about this ages ago after i filled up one time with a bad batch of Optimax....the car ran crap couldnt change gears etc.....i came up with the conclusion that the gearbox is very sensitive in relation to engine..if the engine runs smooth so does the box, so the box itself might not be the only issue here.

I've experienced the complete opposite...LOL

I use to run Optimax for almost a year now. I now use BP Ultimate and I'm still having gearbox issues. I feel that Ultimate runs smoother and I will be sticking with Ultimate as the gears feel a bit smoother but still jams.

I think there's not much difference and it plays a pyschological effect on our minds.

My box has 'issues' with both Optimax and Ultimate, so I'm still convinced it's the clutch... But now Ultimate is becoming more available with the phase out of LRP, a few more BP's here now have Ultimate available... :D :D :D

Yeh, i am using more of Ultimate too because they advertise their fuel better :P

p.s i recently was told to boycot BP and MOBIL fuels because thery are the 2 biggest petroleum companies and if we all buy fuel from other companies they will be forced to cut prices due to more competetion. Don't blast me for this, this was someone else's suggestion but i honestly feel that we should do without fuel in the future. Lets all welcome Hydrgen Fuel Cell and Electric powered cars! :D

Even though it is not a monopoly, we are starved for choice in Fuels over here, look at Europe and Asia where there can be anywhere between 6-10 different companies to choose from. The same goes for the US but the fuel there is c**p anyway.

But these day's I'm walking and cycling much more, and only filling the car up every 4-6 weeks regularly and topping up for cruises and tours occasionally. I agree with your sentiments though Zee, we should be looking at alternative energy, the oil will not last forever, and is not econonical (yet) to synthesize, but one day it will be sold at a premium price (it's still cheaper then bottled water people!!!!!) and who know's what will go on then...

i find depending where ya go ultimate is cheaper than other premiums and my car runs so much better on it.

i dont belive that the gearbox has anything to do with the fuel ya use.

ive noticed that evrytime i take my car to the dealer somthing is different when i get it back.some are good things some are bad.

who knows what the toyota mechanics get upto in our pride and joys. :D

when i got it back yesturday the gears were smooth but the steering seemed heavier and had a little vibration in it.

then again i had drivin a lancer for over 24 hours so who knows.

probably just my mind playing games lol :P

As I said it didnt FIX the issue but did make the throw of the arm feel different. and getting it into 2/3 at high RPM is slightly better.

This could be that the lubrication additives that they use stop a certain amount of engine vibration ???? who knows...........

It works for me and I'll stick to it now.

Each to their own. If you dont agree, dont do it. If you think im full of cr@p, dont do it.

But this is a community...we SHARE information :D

It maybe the fact that you modified the front of your car on a wall that makes it feel smoother. A rough technique I admit Craig but if it works for you and your gearbox then possibly go and hit a bigger wall and see if it elimates gearbox trouble all together! :P :P :P

On a serious note though my car does run better on optimax over ultimate and optimax is more readily available to where I live. As for making the gearbox change better can't comment on that one as I have no dramas with my box as i have a great additive that has probably gone a long way to solve any problem I might've had. :D

      1999 Camry Driver's door locking hatch issue

      It's possible that it could be something fouling or dirt build up, dry, or a broken mechanism, so have a look and give the mechanism some lubrication, most likely though, it'll be the actuator. I found one for a good price on Ebay, $25 delivered: Front Door Lock Actuator Right Side For Toyota Camry 1997-2001 | eBay

      Query about the correct rotors for 2006 ACV40 Camry.

      Hi, I'm looking at a set of front rotors for an ACV40 2006, 2.4L Camry. I got a good price on some RDA's at Sparesbox. However both RDA8112 and RDA7686 show as for my car and I'm wondering what the difference is and if there were changes to the rotors during the model production. So does anyone know which rotor is the correct one? Many thanks in advance.

      It's a simple solution though? Already laying down 60k for a RAV4, so what's another 1k on a phone to make everything work seamlessly? 👍

      Your solution is akin to suggesting that switching to a different car manufacturer would resolve the issue. However, not everyone shares the same enthusiasm for using an iPhone as you do.

      Turboed Corolla Overbuilt?

      that engine will be fine, the rods are the main thing to be concerned about. The 2860 is a decent turbo for the 1zz but in this day and age I'd go for a G25-550. The injectors might be on the small side, we run DW1000's. You need a full length injector, the shorter injectors with adaptors like ID1050x dont fit the 1zz head. You don't need an aftermarket intake manifold, if you do go down that path, avoid the CNC innovations unit, it's garbage. Do the boost control with a MAC valve and control it with the aftermarket ECU of your choice, I use Link stuff on most of my builds with the G4x Storm as the minimum. I also wire a fuel pressure sensor and oil pressure sensor to the ECU in my installs. Use a decent intercooler, the better cores (ARE, PWR, Garrett, Vibrant, Plazmaman, Hypertune) work a lot better than the chinese stuff like Aeroflow. a 450x250-300 fits fairly well with custom end tanks to route the cooler pipes through next to the radiator Don't forget about the clutch and gearbox. These days I like the Uniclutch twinplate, Above 300whp you'll want to think about upgrading the 3rd and 4th gears in the box also with the SSC (Hollinger) gear set and install an LSD of your choice. If you're going to give it a hard time, you'll also want an oil cooler. I like the HKS thermostat type sandwich plates and setrab or mocal oil coolers with -10 speedflow fittings/lines (Chinese AN fittings neck down to a lot smaller internal diameter in their bends, not great for flow) You'll also want to think about brakes, Celica or Sportivo front calipers will bolt on with sportivo discs as a starting point. To have somewhere like Tunehouse do the work you'll want to budget somewhere between 20-40K

      Camry Touring 2010 Fuel consumption 15.2L/100km. Normal?

      I did the mathematics myself regarding costs vs benefits for fuel injector cleaner. I have changed from 91ULP to 95PULP and 98PULP. Price difference can be about 13 -20 cents. Compared to 91ULP, Premium quality fuel should have a better quality additive package designed to have superior engine cleaning capabilities so the engine can perform at their best.

      "Fuel injector cleaner is a waste of money" Only if you by the cheap crap if you use LiquMolly a German Product it does work and you won't waste your Money.
