Question Question on lead in fueling ? - 12-30-2018, 09:21 AM

I got 50 barrels of VP Racing Q16. I know that the engine (n54) I'm driving is not suitable for this fuel. Can I make these fuels available in my vehicle with tuning or something else ?

Nope...lead kills O2 sensors.

It’s actually a great fuel for your N54, we use it on boosted performance motors all the time. It’s fine for O2 sensors, but not for cats. Even trace residue can poison cats quickly, so

You used it all the time without coding o2 sensors or something else ? About cats , Iíve already run ctless dwnpipes for years.

Leaded fuels are great for your motor...but like said before not good for cats. Lead is a great lubricant for exhaust valves...but not good for the environment.

Can’t we use leaded fueling with coding or ignoring the o2 sensors ?

Sunoco disagrees with you about O2 sensors and leaded fuel. It will kill them.

The fuel manufacturer has liability to consider too.
Race applications in general are hard on O2 sensors, regardless of what fuel, my experience hasn’t shown any significant difference in O2 sensor durability between leaded and unleaded fuels, and IMHO they are pretty cheap and easy to replace; a good trade off for the protection that a good leaded race fuel can provide in a high boost application. Granted my version of high boost is probably a bit different than most, my last race car was a 289” SBF with twin 67s at ~55psi and making ~1500hp on C16. Never had an O2 sensor fail in that car over the years I ran it.

That being said, if it’s a street car that may have a *** put back on in the future I would avoid leaded fuels because even trace residue can poison the converters.

The sensors will just die faster, but if you aren't keeping your car on race gas 24/7 wont be much of an issue. If you are single turbo they die fast anyway lol

I am adamant to use Q16 in my n54. Last thing , does it need a special tune or BMS race flash can compensate it ?
