HeavenlyBang:
OP is looking at a 2007, I believe. First-gen.

rationalmind:
Mine is a TL with stated 26mpg which I achieve with regular gas on the highway. Those who use premium fuel get as much as 30mpg on the highway.

I know he can achieve his stated 20mpg on the highway even with regular fuel.

survivex:
Many thanks. On the fuel, i understand that its a 3.7L engine so it can't be compared to those lower. If I get up to 15L/100km in city and less on the highway I am fine.

weyreypey:
For him to be playing with xylene and toluene dangerous carcinogenics ...he must be getting 11 MPG on the highway!!

Rubbiish:
how is avalon fuel consumption?

GAZZUZZ:
call me. Ensure you have history of current issues. Engine size very important, pics also important.

GAZZUZZ:
2days after original post, replacement engine was installed and vehicle left workshop. It's been fine ever since.
Ever found out what happened to the original engine?

HeavenlyBang:
You no dey tire?

feelme3:
All these speculation about V6 engine chopping fuel be wetin I no understand oo. Again I am speaking from first hand experience.

I normally use 72litres (full tank) on my 08 Maxima from Lagos to Onitsha with AC and four passengers (I dey pick guys from toll gate and collect 3k fuel subsidy each which almost covers my ⛽ money ) And this isn't a one time experience. I wouldn't know if that's gulping too much fuel but for me it's an OK deal compared to the stress of commercial bus.

I stay in ikorodu and 3k fuel takes me to Ikoyi twice with other small small waka around. So I don't get this alarm about 6 cylinder ati v6 consuming so much fuel. The only time I spent 5k fuel in two days within Lagos was one time I had a leaking exhaust and one clogged injector. I for craze that period but my mechanic found the issues, change of some plugs, cleaned up the injectors with one spray thing like that, changed air filter and fuel filter and car came back to life. Cumulative spending wasn't even up to 5k.
I still maintain that if you don't treat a car well by servicing regularly, car will show you nwi even if na 2 cylinder or V1 engine.

aylagos:
we decided to get Acura MDX 08 next week but a clean and full option MDX

cmon:
Well, the lexus ages better than the MDX for sure. Once the acura starts getting older, you'll hate it quickly.

HRtechnique:
Okay.
I used to think it has to do with mechanical issues.

alphaNomega:
Since you have experience with the BMW I'd suggest you go for the e90. It's an excellent ride to own and run around.

Any car can be a lemon, make sure you do proper inspection before paying for your new car.

That Lexus IS is just a tricked out Yaris.

HeavenlyBang:
Yes, 1L per tank should be enough to get our octane rating up to like 89 RON or so. It's basically a 1.5% mixture ratio and most engines have a 30% ratio tolerance for Xylene.

Be careful with that stuff, bro. It's carcinogenic. In fact, I wouldn't store 25L of the thing anywhere near me.

Here's a relevant passage on the matter.

HeavenlyBang:
So, I've been doing research on this.
Use this calculator.
http://www.motorsportsracingfuels.com/OctaneCalculator.html
Desired octane rating: 92
Min octane rating: 87 (Nigerian fuel is probably worse but it's a good start)
Max octane rating: 117 (octane rating of Xylene)
Desired gallons is the total amount of fuel you want in your tank after the mixture (20 gallons for most sedans)

For every 10 litres of the total mix you're doing, add 30ml of ATF. Xylene apparently kills lubricants in gasoline, so you need to balance it back so it doesn't eat at your fuel assembly.

Give us feedback.

Edit: According to all mixture formulas I've seen so far, you'd need to use about 1.5 gallons (5L) of Xylene on an 80L tank to raise it from 89 RON to 91 RON.

That said, there's a guy who says he used the 444ml can of octane booster and manage to stop pinging, so I'm not sure. Could be a placebo effect? Could be that pinging still occurs but just inaudibly?

Readonee35L:
The motor na Track car?
Or it's a Twin turbo Engine running jet fuel
All this story here self

fotodaddy:
Experience is the best teacher. Tolded them!!!

Readonee35L:
Na me go enlighten una .

kingreign:
High compression ratio engine. Premium fuel must be required @green highlights.
Unreliability and high failure rates may set in like BMW E90 @red bolded.

3kay945:
I wont mind hearing the timing chain story boss.

You made good comment up there. Though, there are many stuff car owners can do themselves if equipped with relevant tools and information.
At least, servicing and changing of plugs on some vehicles are easy especially some Toyota and rav4 etc.

nurey:
Nissan/infiniti sits above benz in the reliability index, even Audi/VW is above benz.

So you should draw your own attention to your list
