Fuel recommendation

FUEL RECOMMENDATION

Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research octane number 91).

For improved vehicle performance, NISSAN recommends the use of unleaded premium gasoline with an octane rating of at least 91 AKI number (Research octane number 96).

CAUTION Using a fuel other than that specified could adversely affect the emission control system, and may also affect the warranty coverage. under no circumstances should a leaded gasoline be used, because this will damage the three-way catalyst. Gasoline specifications

NISSAN recommends using gasoline that meets the World-Wide Fuel Charter specifications where it is available. Many of the automobile manufacturers developed this specification to improve emission system and vehicle performance. Ask your service station manager if the gasoline meets the World-Wide Fuel Charter specifications.

Reformulated gasoline

Some fuel suppliers are now producing reformulated gasolines. These gasolines are specially designed to reduce vehicle emissions. NISSAN supports efforts towards cleaner air and suggests that you use reformulated gasoline when available.

Gasoline containing oxygenates

Some fuel suppliers sell gasoline containing oxygenates such as ethanol, MTBE and methanol with or without advertising their presence. NISSAN does not recommend the use of fuels of which the oxygenate content and the fuel compatibility for your NISSAN cannot be readily determined. If in doubt, ask your service station manager.

If you use oxygenate-blend gasoline, please take the following precautions as the usage of such fuels may cause vehicle performance problems and/or fuel system damage.

. The fuel should be unleaded and have an octane rating no lower than that recommended for unleaded gasoline. . If an oxygenate-blend other than methanol blend is used, it should contain no more than 10% oxygenate. (MTBE may, however, be added up to 15%.) . If a methanol blend is used, it should contain no more than 5% methanol (methyl alcohol, wood alcohol). It should also contain a suitable amount of appropriate solvents and corrosion inhibitors. If not properly formulated with appropriate solvents and corrosion inhibitors, such methanol blends may cause fuel system damage and/or vehicle performance problems. At this time, sufficient data is not available to ensure that all methanol blends are suitable for use in NISSAN vehicles. If any driveability problems such as engine stalling and difficult hot-starting are experienced after using oxygenate-blend fuels, immediately change to a non-oxygenate fuel or a fuel with a low blend of MTBE.

Shawn === What I understand is there is nolonger any MTBE. being allowed to be used. Now it's Ethanol that is replacing the MTBE. and thats not really good.

It's more like,

"We timed the engine to run on premium gas because the vast majority of the customers who buy a Maxima are interested in the performance aspects of the car. Cheap idiots need not apply."

The engine is timed by the ECM. If it sees premium gas, it compensates just like it does for regular.

Only with certian limits,,,mine pings like crazy on reg under hard acceleration, made harder by the need for the ECU to severely retard the timing. It even pings slightly on Premium - but if you read the maual, this is normal,,

The engine is high compression,,it needs premium to perform and last at its best,,,

Again,,,why the F**** does this thread keep coming up...????? Acuras, Mercedes, BMWs, Porches, and many more HIGH PERFORMANCE Sedans,,,,,,recomend PREMIUM,,,

For Christs Sake....ITS >Rich wrote:

Only the initial ping. Once the knock sensor hears that, the timing is adjusted. If it continues to ping, it is wrong.

Perform, yes. Last, no. Do you work for an oil company or something?

Key word here is recommend.

I guess that you don't get that that is NOT the issue .

No you do not understand the issue,,the charge was that Nissan was commiting fraud,,,THEY ARE NOT,,,,,,,> read the maual, this is normal,,

Ever heard of warranty?

I am a mechanic by trade. You are a chemical engineer and are clearly out of your element. Tell me how gasoline is made, do not try to tell me how the car works.

You could no more tell me how an internal combustion engine, with an ECU system, and an anti knock sensor works; than my plumber could explain how gravity and the unified field theory makes my toilet flush,,,,

The warrantee will not cover pre ignition damage to the engine,,,and even if it did,,apparently running a car more than 60,000 miles isn't in your book of tricks,,,

Its simply DUMB to infer, recommend, or advocate running sub standard fuel in a high performance vehicle that up front tells you you need premium for optimum performance. One sub standard tank of Reg gas, that the ECU can not retard the timing enough on and you have got 7 grand worth of scrap metal under the hood.

But then again,,,you are a mechanic, and thats how you make your living - fixing broken things.
