I GOT YOUR FIRE FOR YA!!

Like every thing in life the answer is IT DEPENDS!! For the most part cetane boosters are not needed but in the past some parts of the country had issues with low centane (wisconsin area was one if I remember right). Additives like anti-gel are great to have around in the fall or if you get a unexpected cold snap 30-40 degrees lower then normal temps in the winter. Remember fuel is blended for the temps your area is expected to see, a truck filled in Aug may jell in November. Real cold air intakes work ask any pilot (carb heat decreases RPM by 100 or more). Non of my Diesel fuel sits long enough for a stabilizer but the mogas does, I use Sta-bul for all my gas engines that sit for 7 mo over the winter. For the most part I just fill and go but I keep some snake oil handy for appropriate times or emergencies.

I think most of the effects seen from the COLD AIR intakes are simply from improved airflow. The HP numbers are usually noted at redline and how many of us run at redline all day long?

No, that's not what he said. I am wrong to infer what anybody says. I apologize for that.

I failed to add the smiley emoticon to indicate I was playing along.

I like the additive debates because there is no definitive answer and solid arguments have been presented for all sides.

I hope Spring has arrived up your way.

To add to this: It does depend. If you don't use any additives then you never know what will happen. If you use only ONE specific brand then you will never know what happens when using any other brand.

All this even applies to the fuel station you select. If you just use one brand (Shell, BP, etc etc) you never know what may happen using another brand (Murphy, QT, WaWa, etc etc). Yes, one does need to weight the fuel quality provided by the station. I'm not saying use known bad fuel stations "just to see what happens".

I will say this in my area of travels I have used quite a few different brands of fuel. Pretty consistent results tell me where to refuel. When you get fuel from a previously "unknown" source and your MPG jumps 1-2MPG you start asking yourself questions. I'm fairly convinced as a Wal-Mart/Murphy station I use has something "in the mix" that gives me awesome fuel numbers. I'm testing the stations in my local area to see what happens. I may even make it a point to try using Murphy on my next trip South just to see if the gains are held up. There is a station a ways away from me that uses 50+Cetane diesel. I haven't been able to get there for a test run so that may happen over the next few months.

Not trying to change this to a MPG post but people need to get out of the singular mindsets of the past. Embrace the options, see what happens.
