Shell V-Power (premium) has a lot of detergents in it, much more
than the Top Tier threshold. Shell primo is Tribologist Terry
Dyson's favorite gas right now.

He likes it with ethanol in the premium, too. Like lotsa folks,
I'm not keen on 10 percent ethanol, though.

I doubt if the best gas in the world will eliminate the condition that the
OP is describing, and it is not necessary to use premium fuel in a Corolla.

Well, you mentioned the OP should try Chevron Techron
fuel injector cleaner. I was just noting that the
detergent additive in Shell V-Power is preferred by
Tribologist Terry Dyson more than the Techron that
comes in Chevron gasoline.

Once he gets his injector problem resolved, he can
opt for a brand name gasoline like Shell V-Power,
(regular grade or premium).

I also mentioned that a dirty MAF sensor is more likely to cure the
condition than cleaning the fuel injectors.

Perhaps TOO many! I get horrible mileage with V-Power, and since I get it
in VT it's 'real' gas.

I get better mileage with 2nd tier E-10 Premium than I do with V-Power!

I think Terry Dyson is overrated and thinks he knows more than he actually
does.

[Chuckle] Well, I think Mr. Terry Dyson of Dyson Analysis is
a renowned tribologist with decades of experience who analyzes
UOAs on a daily basis. He can see, for example, the effects of
different brands of gasoline on engines that have
fuel dilution blow-by problems, piston ring problems, etc.

Finally, people don't pay him $60 per used oil analysis for
nothing, especially when you can get a used oil analysis from
Blackstone-Labs for ~$23. But North America is about
diversity, so you're welcome to your opinion :-) [Lol]

Why don't you elaborate on this, Hachi. Give us some
concrete mileage numbers. Interesting :-)

My unsolicited opinion is that used oil analysis is, for the most part,
a waste of money.

========================

I have to disagree here. Huge fleets and sober, bottom line
minded trucking companies employ Used Oil Analysis on an
ongoing basis to protect their costly engine investments.
