Oil Pressure/Temperature guage????

Mobil 1 synthetic lists the flash point for 10w30 at 220*C (428*F) and 10w40 at 227*C (440*F). I doubt you would see any difference in the two grades boiling in our engines. Three oils I'm looking at are probably not correct for our bikes, but I would not expect too much variation.

Thanks for that info. I said F and not C, my mistake. Corrected.

Mobil 1 Racing 4T:

Flash Point, °C (ASTM D93), 212 / 413.6 Degrees F

Bob the oil guy's review:

Flash Point, ºC, ASTM D 92 253 / 487.4 Degrees F


No idea why the difference?


I could not find any specs on the GN4 that honda recommends for our bikes, but I did find this:

Pro Honda GN4 - Black bottle/red label. Intended as an all around 4-stroke
oil motorcycle for normal everyday riding; low heat applications. GN4 is a
petroleum-based motorcycle 4-stroke oil recommended for scooters, ATV's and
motorcycles used for light duty and low heat usage. Commuting, normal street
rides, casual trail use and low engine stress situations do not cause as much heat
to build up in the engine therefore a less expensive additive package can be
utilized. This is our original motorcycle oil formula developed specifically for
motorcycles and blended with an additive package to meet the unique shifting
requirements of shared engine and transmission sump designs. GN4 is packaged in a 1-litre black
bottle with a red label, available in 10W30, 10W40, 20W50 and also 5w30 weight for cold
weather ATV use.
