i thought only chuck norris did that

i am running 30W quaker or pennzoil (they are basicly the same company) change it about every 20 hours, i cheat and do the filter every other change. I use an AC delco filter premium brand and a fraction the cost of mercury.

i also believe in filling the engine so it is just over the add line, less less resistance for the crank to run thru and less chance of foaming. my two cents

Thanks for the info, I usually have the marina change the oil on this boat because its easier for me. They say they use the merc oil but I want to be sure whats going in there from now on.

I was wondering about the synthetics as I heard in the past they hold up better to higher temps ect.

I dont put many hours on the boat usually 50 - 80 a year but now I am doing more trips and want to change the oil more frequently and with the same oil every time.

Thanks everybody

I have always ran Valvoline Race 40 in my 502's and never an issue. I currently am using Merc 25/40 but now that I am out of warranty I may switch to Valv.

Thats because AC does not make the merc filters Wix does...and Wix makes a much better filter then AC does



Just my 3 cents

Wix Racing 1061R direct from Napa. Best filter you can put on a 500EFI.
(1060R for the 496Mag/HO)

I read that the Wix filter is better because the filter isn't paper that is prone to swelling up if any water gets in the oil at all.

[QUOTE=Strip Poker 388]Guy's He admits ,Since he doesn't change the oil religiously I doubt he will buy synthetic.



I was thinking the same thing! I also would never post something like that here especially when the boat in question is in the classified!

Wix Racing is very good if you want a heavy case that won't blow and a good filter too.

K&N is very good.

Fram Racing is about the only thing I see on racing engines these days...

I am very surprised everyone has not gone to a PAO synthetic oil...the data is in...it is superior...

I use Amsoil synthetic motor oil, trans, and gear lube. It lasts longer and does not break down.
