[rich seibert]

Valvoline is supposed to have the highest content of zinc or somthing in its formula, from what i remember from what i have read in the past,
back in the day i was chief oil changer on a top fuel hydro from NJ
triple digit racing

Castrol Syntech pure synthetic (not the blend), 5W-50.
I feel this is NOT a true synthetic motor lubricant. It ain't a bad oil, but if you're going to kick down the big bucks for a synthetic lubricant, get a real one and not a petroleum based molecule that was restructured in the lab. Castrol Syntec used to be a true synthetic lubricant, but they quietly changed the formula (starting with dino oil now) and the public didn't know it...until they were taken to court by a group of synthetic lubricant manufacturers.
All the synthetics mentioned above are good lubricants...Torco, Royal Purple, Valvoline Racing Synthetic, etc. I myself use Mobil 1 or Amsoil and have two 12-inch tall, 7-micron rating oil filters. The petroleum-based Valvoline Racing is also a very good dino oil.
Lubrication has come a lo-o-o-o-o-ong way since the time most of our ***boats were built and just about all of the oils out there are superior to what was available at the time of the motor's orignal manufacture.

[Blown Away]

Valvoline Racing, 50 wt

VALVOLINE RACING learned it from my dad

[1978 Rogers]

mobil syn 15 or 20-50. The one with the red cap.

[pacman]

LUCAS semi synthetic 20 / 50 ive had great results in both my boats and if i wasnt getting sponsored by them i would still spend the extra money

[RiverRacer]

14 quarts of Valvoline straight 50 wt Racing Oil(NOT legal for street use type), because it's not a "street" JetBoat. RR

[LVjetboy]

Mobil 1 15-50 synthetic. Without an oil cooler, jet boat oil typically runs very hot...250-280 F or more. I think the higher temperature resistance (to breakdown) of synthetics is worth the expense even for a 10 qt pan.

[Mr. Crusader 83]

20 50 here non synthetic

[jetboat468]

Royal Purple or BG Synthetic is the only way to jet :rollside: the extra expense is well worth it We sell them both at our store.

[Liberator TJ1984]

10 qts. Syn.Royal Purple 20-50 & 2 qt.Lucas Syn.Oil Treatment

[roostwear]

I've used 10w-40 Castrol blend since I built the circus boat's 460 3 years ago. I have around 100 hours on it since then, and pulled down the bottom end Sunday for inspection. The rod and main bearings look like the day I put them in 3 years ago. Don't know what else I could ask for in an oil.

[Blown Away]

With valvoline I can run 40 psi of boost 40 degrees of timing on pump gas,the moter makes 1 million hp.Plus if I drink too much on a saturday night I just I drink a qt. before I go to bed and I don't wake with a hang over .Now that good oil!! :rollside:

[n8dawg]

Castrol 40wt. thats what I've used since my younger muscle car days. And because of John Force racing for them!!!!!! :crossx:
