great it sounds like it would be dam hard to get too much cetane that is the answer I was looking for....

I have been from side to side of this country and never saw cetane higher than 45 points. Usually it varies from 40 to 42, with premium diesel being 45 points.

I can only say that running too much cetane with excessive timing advance will cause ping...I ran a RokkTeck Sensor and noticed the advanced timing with 45 cetane caused a bit of "ping" in my 04.5...

my brother just bought a cetane booster used by the super farm tractor guys. one ounce per gallon of fuel is recommended for street use and it raises the cetane rating 10-12 bars. the super farms guys a ton more than one ounce per gallon and i didnt hear anything out of the ordinary with their motors.

I know a few people who run it but i think you would want to maybe ad a lubricating agent too if you put pure cetane in your tank. I talked to the guys at scheids about it a long time ago and they reccomended it if i remember corectly.

And what is pure cetane?

I dont know really, Me and shane were out at a buddys house to do my turbo and injectors and he showed us this stuff in a galvanized looking metal can that he uses but it is rediculous to buy it costs alot. He told me to call scheids and they sell it.

It's probably toluene, MEK, or the like; that the oil companies use to increase "cetane"...Again, cetane is a rate-of-burn thing, the additive only increases or decreases that rate-of-burn number...but the additive itself isn't "cetane", but more correctly, it is probably a "cetane booster".

never thought of that .........if it is toluene be extreamly careful not to get any on you

WOW............check out this shit I found



2 Cycle oil is a HIGH BTU additive (138,000 BTU's) compared to most cetane booster that are low BTU's (~19,000 BTU's <- NO TYPO!). The more you use a cetane booster the more your wasting out your fuel. This will reduce HP/TQ (Been tested) and also reduce MPG (Been tested). Think about how we all whine in the winter because the MPG falls (HIGH CETANE FUELS). Then in the summer time we all relax again (LOW CETANE FUELS).

whoooaa. so if this is true then it contradicts mike's research. something's off.
