Have a look Miles. You've nothing to lose. First I've seen/heard of that neat trick.

Seems that way Vlad. Will keep you you posted. Thanks for dropping by and take care

Today I embarked on a 130 mile motorway journey as my quest for the best mpg continues. Before setting off, I filled up from empty with Texaco. The end result was very surprising, I averaged 53.9mpg across the entire journey. I can't be sure if this increase was a result of different fuel or whether it was that my ECU took longer than quoted 500 miles to learn its new map. One things for sure, it wasn't a change in driving style. I'm pretty sure this wasn't an anomaly and as as such am really happy with the figure. If I can maintain 50mpg+ on the motorway, I'll be well and truly pleased and it will fall in line with previous similarly sized diesels I've had before. Loving getting to know and understand my first Lexus.

I should add this figure was achieved whilst in 5th gear maintaining a speed of 66mph.

Can anyone shed any light on fuel filters being seized? I've just spoken to my garage today and they explained there are two fuel filters and one of them was seized so unable to extract without potential breaking the housing. Does anyone know if this part is easily sourced and whether or not it is costly?

Many thanks

Hi Miles. I'd ask in the gen 2 IS section of the forum as this thread is in the new members. You'll get a better response.

Do you have a link to the gen2 is section?

Don't be daft lol. Are you using a laptop or phone to access the form?

Either way top right of screen on homepage or any page hit the 3 horizontal lines. Drop down menu go Forums then a new page appears with all the Lexus models IS GS LS UX etc.

Hi Tom. Welcome to the best Lexus forum there is. It would have been better to introduce yourself with your own thread. More of us would see you.

Glad to say I'm back online. Still no contact or explanation from admin, but I assume the content moderation ban has been lifted thanks to @steve2006 Still have 3 warning points applied and message function still disabled 🤷🏽‍♂️ Anyway, will continue to post on my experience as new Lexus owner. Much to discuss. Thanks to everyone who supported me and reached out over the last three weeks 🙏🏼

And about time too. Welcome back Miles 👍

So after completing 6k miles since having the car serviced, I decided to switch engine oil from Quantum 5w30 to Millers Nanodrive 0w40. An oil I've used many times before in both petrol and diesel engines. As well as using Oilsyn Release-Tech engine flush. Since said change, I've completed approx 500 miles (450 motorway miles) and I have to say I've noticed a remarkable difference in smoothness and a huge uplift in mpg, the car also seems to start instantly, whereas before it would labour very minorly. Previously I was averaging 53-54mpg on motorways with a tank average of approx 49-50mpg and a full range of around 530 miles per tank, but on this most recent tank I averaged 57.5mpg across the 500 miles and full range is now 580 miles. Obviously a huge improvement and with driving c.800 miles a week, I stand to save around £15 a week. I will report back the tank average on a more indicative week where I would expect to do 70/30 extra urban/urban. 

On another note, I've noticed a couple of minor flatspots in 4th and 5th gear, which my existing mapper can't iron out, blaming it on the DPF, so I've booked the car into Japanese tuning specialist in Plymouth, for a custom dyno map, they say they will be able to fix the issue easily enough and will inspect the DPF too, even if the DPF is 'clean' as they put it, they actually advised I did away with the DPF and EGR entirely, but I'm wary of doing that, just as I am talking about it on this forum, after recently being singled out and attacked for even discussing the matter. The tuner I spoke to explained that a properly maintained car without DPF/EGR will in all cases be less emissive than a poorly maintained car with a DPF/EGR and infinitely more reliable, he said "I've seen it with my own eyes on hundreds, if not thousands of examples, all you've got to do is stick an emissions analyser probe in the tailpipe and you can see for yourself. The reason DPF's came about was to mitigate all the diesels that aren't used for their intended purpose or aren't properly maintained"

Post amended (because I can't edit) with the omission of a quote from a tuning company pertaining to DPF removal. Thanks @steve2006for the heads up.
