It is not that I am pinging all the time and what not. I would have surely have blown my engine now for the past 18 months I have been running this tune. I did not tune it myself as I know nothing about tuning a car. It has been street tuned and then A/F logged dyno tuned. I run 93 cause my car is tuned for 93 and that is all I will run. I can see how running a lower octane fuel could cause problems for me so I usually do not run it. I do not know but if it makes you feel better saying I am tuned on the ragged edge all the while burning no oil and using no coolant is fine with me. I think I would have blown it up by now if that was the case.

I never said that at all -- cleaner higher octane fuels burn more complete and leave less deposits especially nitrogen rich fuel additives such as Shell V Power.

Quality fuel (and source) is the most important thing. Buying 93 from a Station in Bumbleweed City, that's been in the ground for a year is going to degrade regardless of fuel brand.

Phd Oil Manufacturing engineers --->>> YOU and YOUR band of expert tuners.

that is evident. there is no power difference but I assure you there is a difference in the internal effects and dynamics of your engine over time.

The 'quality' of fuel makes ZERO difference over a car sooting/dirty black bumpers/ etc etc. That's the tune itself. . Heck my Maxima is rated for 91 or higher. I run 87. The tail pipe is as clean as a whistle. I guess that 87 is just junk right?

lots of things can led to carbon build up. Would it not make since to run fuels that have been proven to reduce and help carbon deposits left within the engine?

Nope other than running Shell V Power 93 in most all my vehicles and the increase in performance and the ability to see how my cars react differently then when I run some MFA 93 or whatever?

Why tune on the ragged edge and restrict yourself - you drive a street car, not a race car. Hell my car sees a boatload of track time, yet I still regard/build/maintain it like a street car. I'm honest with myself, and realistic about the cars. That's the difference. (I run Mobil as well because it's the cheapest synthetic I can buy, and Rotell Diesel grade oil in my Maxima as it's what we have in tanks at the shop, Maxima has 250k on it, 40k of which I put on it. Maybe I'll switch to what the magazines say is best right? LOL)

run what you want and I will continue to run what I want. How do you know you have no knock -- knock really can not even be heard unless it is really bad and by then it is too late. I have the ability to see knock counts when I hit higher boost levels, How about you and your ROM tune?

Let me ASSURE you that the guys in the Fuel Yards are pumping whatever fuel from the brand/carrier's tanks into their trucks and its' going into their specific gas stations. There isn't any sort of proportioning or 'shell gets the top, exxon second, BP last' as it's all pumped together. It's also filtered before being pumped in trucks, as well as in the tanks before it goes in your car, as well as in your car itself. Bottom line, Have you been to a fuel yard? I have. The only stuff that is often 'hodge podge' are some of the Farm/Fuel ones that 'country' gas stations get. It's whatever the cheapest supplier at the port/yard sells that they buy.

correct but once the fuel is sent to the dealers tanks the fuel additives are added to them. They Shell, BP, or whoever add things to the fuel which is their own branded substances such as V-Power or whatever.

so you want me to accept that you know everything about tuning and I am just a newbie no nothing. I have read some of your ingenious creative ways to make a ka compressor work with an sr motor or how to run another alternator than the one mentioned for the sr. You do know that the sr a/c compressor is like hella lot smaller than the ka one? right? Some of the stuff such as the sr iron manifold extrude hon process is great but some of the stuff like the alternator solution misses the mark IMO. Your car or anyone that owns a 240sx sr20det swapped car on this forum is only as good as the parts placed on them.
