Another newby question.. What oil should i be running in my 54 235? not having smoke issues but ive been using 30w non detergent. Good or bad? i have a slight knock now hoping itll clear when i do my valves hopefully this week.. is my oil too viscous??
Uh..OHH! The annual Favorite Oil Question...let me take cover first. I like Mobil 1, 5-30...my 235 and for that matter my 216 is very happy on it. Let the shooting begin!
Flame war !!!!! Let me say in advance : you're ALL wrong ! .(even those who agree with me . Back on topic , use the thinnest DETERGENT multi-vis oils you can find , synthetics are best . Does it knock under load or when you let up on the throttle ? . Might it be piston slap ? .
Why nate, it sounds like we agree on this?? Or maybe I was won over in some previous year. Everything i own is on Synthetic Oil......price is hardly a factor anymore.
Before the "oil wars" start, just let me say: As long as you keep oil in it and change it religiously, it doesn't matter what brand it is. Ready, set, go...
My Opinion... I prefer 10W-30 in either dino or synthetic blend. I definitely say detergent oil, if you have an oil filter. If you don't run an oil filter, I would stay with non-detergent oil until you find an oil filter to use. As always, no matter what oil type or filter or no, frequent HOT oil changes are a must!!!
Let the oil wars begin...... ZDDP my son.... ZDDP.... http://www.hotrod.com/techarticles/engine/flat_tappet_cam_tech/viewall.html I use Shell Rotella T oil in my fleet of old trucks.... Its the same oil I use in my dail driver Cummins turbo diesel truck & it is loaded with ZDDP.
thanks for responding. It actually only will knock a bit under load. i can increase rpm but only gradually..
You guys are gonna love this... I use 20/50 oil and I have a 10 Qt. oil pan and 2 oil filters....Big Tim
I got several gallons of Rotella Diesel engine oil for bout 75% off a few years ago. I like it because it has increase wear protectors, zinc I guess. But once its out I will try to find the cheaper synthetic I can get. But I have been running that for the last 3 years with no problems. I would say 8-10K miles, changed 4 times. But then again I have the GMC, with oil pressure Ok now I really have started it!!! Go
