I have an '06 350 with 40,000 miles and was wondering if I should be using some type of fuel injector cleaner once every oil change? Or will I be wasting money? Thanks guys!

 

just use good quality premium gas and you be fine,

 

I agree with Shervin, as long as your using premium fuel with the additives you shouldn't really have to run fuel injector cleaner in the car. Some people do it every so often just for extra piece of mind though. I've done that myself, not expecting to see a noticeable improvement when I do though.

Premium fuel + Synthetic oil = You are good to go

 

I started to use it on my car at 50k. It made no noticeable difference, and I didn't expect it to; but I do it just for the extra piece of mind.

There's no evidence of our cars requiring a fuel cleaner, there have been plenty of IS350 that have made it past 100k without a fuel cleaner. For the 250, I would say its necessary, but for the 350, if your willing to spare $6 go ahead

 

I did it at 30k for shiggs and giggles. Figured it wouldn't hurt and prep them for the 60k change...

 

If you must try this stuff a tank before your next oil change. Like they said. Piece of mind.

Thanks guys....I have never used anything but premium, super plus gas since i have owned it at 30,000 miles...i just didn't wanna make a mistake by running fuel injector cleaner if it is not "recommended"...

 

it wouldnt hurt, but not necessary

 

is costco gas premium gas okay? for some reason my brother had a belief that its *****. my dad uses it for his porsche though

 

my is 250 was idling weird 8-10 month idling weird after i started using costco gas. Switched to shell's v power and problem went away.

 

I wouldn't say one gasoline is better than the other, everyone has their beliefs of their preference over the others.

Personally, I always use Shell V-power (91). Never had a problem on any vehicle.

 

What's the difference between the two engines that makes you suggest its needed on the 250 ?

 

He's probably referring to the fact that the IS250 motors suffer from Carbon Build up issues. But, it still won't make a difference because even if you pour fuel injector cleaner into the gas tank of an IS250, it will never touch the areas where the carbon build up exists because of the Direct Injection design.

 

Waste of money. It'll be better used to wipe your ***.

 

The manual says NOT to use these products if I remember correctly
