Just alil survey.

Amsoil all the way here.

I'm runnin Royal Purple. 10-30

mobil one synthetic, sythetic because im running mods, mobile one because royal purple is shit, and couldnt find amsoil locally

Royal Purple is shit????

Well what the Fuk BJ you and coondik were right there looking at oil with me the other day why did ya'll let me get that shit then??? WTF

Royal Purple synthetic

I use the cheapest oil I can find. It's a lawn mower engine. Rotella 15 w 40 works great.

Mobil 1 extended performance is the ONLY 100% realy synthetic mobil offers. the one that sayd fully synthectic is still petroleum based. I run sythetci becauser its a btetter oil. Look up an independant survey and compare the molecular structure of sythetic oil compared to Dinosoar oil. You will see synthetic has a smooth molecular shape compared to Dino oil whick is really jagged and rough looking.

i think mine has tractor oil in it, but i dont know. Im with craig Rotella T 15w 40. if its good enough for the dodge its good enough for the lawnmower

Mobil 1 synthetic

I'd be interested to see what yall have to say about this:

I was told we should be running a heavy racing oil? I was told that our engines run hot and can literally break down the oil because of the temperatures were running our engines at. Thus, we change oil every 15 hours... I know mines dark and black each time I remove it.

I'm curious to know how many of yall have tried a heavy racing oil as I was told it would provide less friction & therefore less wear when the normal synthetic oils would start to break down.

Oh, I'm running 10-30 Mobile 1 Synthetic.

I changed the oilt that came with my motor at 15 hours. I replaced with Mobil 1 and I now have 52 hours. Oil is a little darker than when I poured it in but it still has a honey tint to it. Not black at all.

Amsoil 20-50.

This is the best site I have found for oil research and literature.

Yeah coondik likes the tase of it too!

Mercury Quick silver 4 stroke 10w30. I gets it cheep and it works.

Royal Purple Sucks........The End!!!!!!

Well I was running 10w-30 mobile 1. I just went to 15w-40 valvoline premium blue because I run it in my cummins and I have a lot of it. We will see what it looks like in a few hours.

Castol sythetic or sythetic blend, It's Liquid Engineering!

Coondik, You say change oil often, How often? I change mine every 100 hrs and its black by around 30 hours, pitch black by 100. Oh, and im running any synthetic 10 30 thats cheap from walmart. Maybe I should change my oil and scheduled oil change.

Some how I thought everyone was changing oil around a 100 hours. I did not get the 10 hour memo. Well I know what im doing tonight.

If it is a stock engine.You DO NOT NEED TO CHANGE IT EVERY 10 HOURS.Change it at 50 hours.Or when it gets dirty.

I change my oil every 15 hours and filter every other so every 30 hours for filter...

Dammit, now I have to go home and change my oil.
