Thanks very much phillip1978, I normally go to Lexus of Blackburn and will ask them if they follow the same method as you described. I saw an earlier post saying they didn’t but hopefully enough people have been asking since that they provide this service now. If they don’t I’ll head to Lexus of Brighton to get it done correctly. My car milage is just under 90k and I think it will be good to get it done now. Do you remember what they charged for this? It’s due for a service in the coming weeks so I’ll post an update. Thanks again and have a great weekend

Well I I am really grateful about the information shared in this discussion and can see it’s been a while since this topic has been discussed. I wanted to look at booking my IS in for a gearbox oil change at Kewish Automotive too, but it appears they are no longer in business (listed as permanently closed on Google maps)🙁. Does anyone have a recommendation in the East/South Eastern suburbs of Melbourne please? Many thanks

The fact that it is only happening whilst driving uphill would make me suspect an exhaust related issue from the cat onward I would start there

Hi Brewsta, i have experienced this with some of my cars in the past and was advised it is unburnt fuel in the exhaust system. Some brands tend to be worse than others which may be attributed to the additives they use. I only use one brand of fuel now and don’t experience this anymore with any of my vehicles. I would recommend trying to fill up at least a couple of times with one brand then assessing the result until you find what works. Good luck!
