Maybe. Could be. Filled up with Exxon 93 a couple days ago though and havent noticed any pinging or the sound Im thinking is pinging. Im thinking 87 isnt the most ideal fuel octane I should use. Yes it runs good and I get good fuel economy on 87 but the pinging worries me as far as potentially doing long term engine damage. Or maybe I have carbon deposits? But how much carbon buildup can there be after 20k miles and using quality gas?

The more timing advance you have in the ignition the higher grade of fuel you need. The 1NZ has a very conservative timing advance compared to the Civic SI and that's mostly why it needs high octane fuel.

If you were to run a stand alone EM and bump the timing up on a stock motor, you'd gain a bunch of power but you'd also require high grade gas.

Good info. Thank you.

And as far as reliability and forced induction, did you mean to say they haven't lowered their compression ratio?

yup, he said it better.

And yes, i am almost positive none of the boosted guys have lowered compression.

^ Garm and Parmas are the only ones.

I actually only run 89 now with no issues. It's incredibly unlikely the noise is actually pre-detonation.

Well I haven't heard any pinging sounds since switching to 93. Would there be anything else that would make a pinging like sound that would improve by switching to a higher octane fuel? I'm wondering if the ethanol is having an affect on the octane rating?

100% E10 use since new, no pinging on 87 octane under any circumstances.

Hmm. Maybe it isn't pinging. I wish I could record the sound its making but its so faint.

R2D2 · 06-09-2011, 08:51 PM

Also, sg11 you are correct there is less energy in the ethanol so ethanol blends contain slightly less energy. Many here report mileage losses when they had to switch over to E10.

yea.. i just dont see a stock new 2010 yaris pinging.. unless u can take it to a dealer and have them verify the noise and do some investigating.. I dont think u really have a problem

Based on what you said, and I guess based on the fact that I have 3k miles left on my warranty, I was wondering if I should take it in to Toyota to see why I'm pinging... Is this something they'll chalk up as just what gas station I fill at, or will they actually do some tests? And last but not least, is a pinging problem something that a warranty would repair?

ChitownY@Ris · 07-07-2011, 06:23 PM

^^Disregard. Just called Toyota. Says he has to do tests to establish the cause, which could take several hours. Additionally, he wasn't sure if Toyota would honor said causes under the warranty. There's no way of knowing until he finds the cause, and submits it to Toyota warranty center for approval. If approved, customer pays nothing. If denied, customer gets charged $107.00 for the diagnosis.

Pretty risky.

In the meantime, he recommended getting gas only at BP or Shell for at least two full tank cycles. If pinging stops, great. If it persists, bring it in to the dealership.

Yep. sounds like a dealership thing.. Also, see if you can get them to pull up a newer yaris and compare the sounds with the service writer. If you can get the service writer to confirm thier is a difference in noise, then you have a better chance of the mechanic to do proper tests instead of just saying "working as disigned", "no problem found", or "normal for this model".
