Never! I dont even shop at costco let alone use their gas.

I have always used 91. There is a gas station near my parents that sells race gas 100 octane! I might try that and see if that helps!

O/T nothing wrong with Costco gas or any other off-brand fuel. It all comes from the same refineries.

It may come from the same refineries but it's nowhere near the same specifications or have the additives packages as the name branded products. There can be a huge difference in quality specifications and driveability index between the brands. Company brand reputation is huge in the retail fuel market. No name brands don't worry about their reputation only there costs.

Ever wonder where the gasoline/diesel blending mistakes wind up going to?

Point to ponder: Ever wonder why there are no name branded Jet Fuel distribution companies at airports? It's called liability. The Jet fuel companies are responsible and accountable for their fuel quality they put into a airplane. Reputation, accountability and not to mention lawsuits are powerful motivators.

My car still has a valve tap like crazy. Took the car to the dealer and listened to another 2010 Z with the parts and service manger, and it sounded somewhat similar, but my engine def sounded louder and more tappy. He is having a field service engineer come out on monday or tuesday to listen to it. So help me god if he tells me it sounds normal. I'm gonna try and record it see if anybody else has similar sounds.

I have learned not to buy something just because its name brand. If anyone really wants to know why they should choose say Chevron over Arco have their gas tested to see whats in it. That is the only way. Otherwise I have a chip for sale that will boost your car 24mpg only 19.95 plus S&H.

I am going to recommend this before Modshack does...run a bottle Techron Concentrate Plus in your gas tank and see what that does. Also, what vehicle did you have before this as injectors can be very noisy at times and if you are not accustom to the noise then the first time you deal with it is always appears odd.

My last car was a 06 Scion TC, and it never knocked or ticked like this. My car before that was a 93 Mitsubishi 3000GT VR4 and that had lifter problems that sounded very similar to this. That's the reason, when I heard it I was like oh noooo lifter problems again? Should I reset my ecu after I use this Techron stuff? Thanks!

No need to reset your ECU. Also, the Mits 3000GT has very noisy injectors, but that car can run up to 200K miles before any real problems with its engine. The VR4 biggest problem was its AWD with owners that did not service ALL the fluids in a timely fashion. Super cool car though.

O/T Ya that car was a dream, I could drop clutch it at like 6800 PRM and it was gonzo! I ended up dropping the tranny after about 138000 miles, replaced it and still sold it for $14000, mind you I bought it off my ex girls mom for $11,000 and it had 56,000 miles on it. It handled like no car Ive ever driven (except of course my Z

) it was so nice to say

to my scion!!!

Ticking injector noise seems to vary.....You should hear a 1.8T Turbo VW/Audi motor! They are, after all, just electrical solenoids being opened and closed.

Techron is good to keep your fuel gauge senders AND fuel injectors clean. I generally do a bottle at every oil change. No need for a reset.
