Scott, even in the great white north it was 100 degrees here yesterday. Even in summer I had bad knock on startup when I tried that thick oil. scared me so I drained it out.
Ive heard alot of good stuff about this oil- Im having some pressure issues right now, and Id like to switch to a little thicker oil to help me out. I am running Valvoline 10w-30 right now Jim- do you suggest I stay with 10w-30 when I try the Brad Penn or try a different formula?
Heres a couple of places that seem to carry it----> http://www.allzim.com/acatalog/Brad_Penn_Oil_-_The_Green_Oil.html and----> http://www.engineproparts.com/BradPenn.html
I just ordered a case from the main Illinois distributor in Rockford Ill. If any Illinois residents on here want some Brad Penn, let me know and I'll post his contact info. Jon
I would think this is your call. If you are wanting to try the thicker oil, go ahead and see if it works for you. I don't thik you will do any harm, it is a partial synthetic and has a pour temp of -27*, much better than the Valvoline I am sure. On a selfish note, I am curious to see, if you notice less of a difference in cold and hot idle pressure, with the Brad Penn. An expensive experiment, but of value. That is my rub, with conventional 10W30 oils. I like 20lbs plus hot oil pressure. With conventional 10W30, it was 15 to 18 lbs. Accepable to be sure, but eh... I will probably be mixing the 20W50 and thw 10W30 together in equal parts. i will then have 15W40, what I am running now, except in diesel. In a perfect world, I would like to have the 20lbs hot oil pressure, using the Brad Penn 10W30. (Thats why I want you to try it first.:laugh: ) I may have to try, to satisfy my own curiosity. Either way, I will be using some form of Brad Penn. Good luck. Regards, John.
According to his sig he has a SBB. Do those have different(better)oiling systems than the BBB's? Would his results be applicable to what we have?
The dealer on ebay custom blends the 15W40 Penn Grade 1 racing oil. It is about $44.00 for a case of 12.
Yes I have a sbb. I seen this thread and it was exactly what I wanted to know... so instead of asking the questino on a new thread I just asked it here. 15-40 is more of what I was thinking, how does the dealer "custom blend" it though? Sounds kinda fishy
Do a search on Brad Penn Oil on ebay. On the auction that pops up, you can ask the sellers anything you want. They are easy people to deal with. They mix 20W50 with 10W30 I think. The 15W40 that Brad Penn offers is for diesel trucks. The blend on ebay is the Penn Grade 1 racing oil.
Just changed my oil from the Rotella 15W40, to the Brad Penn 10W30. 84* here today, car running down road at 175*, at stop lights and extended idle, creeps up to 180* to 190*. Get moving again and it goes right down to 175* to 178* again. I am comfortable with that. My findings... The Brad Penn oil gives me 15 to 18 lbs of hot oil pressure, in gear. After 3 or 4, 30 min heat cycle driving events, and engine starting out at around 190* (after sitting off, for 10 mins.) She seems to settle in at 15 lbs hot idle pressure in gear at 180*. In neutral, goes up to just under 20 lbs. In my car, there is no difference between the Rotella 15W40 and the Brad Penn 10W30. At least I did not go backwards, with the 10W30. I will leaving in for a while, but when I decide to change it again, I am going to mix the 20W50 and the 10W30 and see what happens. If I don't get what I want, I will go with the 20W50 by itself. Kind of redundant and expensive, but it will give me peace of mind. (I am also kinda anal I guess.) They say the first step to recovery is admitting you have an issue.:Brow: :laugh: I'll keep ya posted. Regards, John.
Devon, The pressure is in the 65 to 70lb range. (Kinda hard to get an exact read, could get a passenger, to check.) It really never changes much on the high end, no matter what I put in there. I think my system is safe upstairs, just have this whacky notion about 20 lbs hot.:idea2: I guess I keep reaching for it, cause that is what my stock Stage engine used to run with 10W30. To be fair, I know that the cover on that one was replaced, with a better used O.E. one at one point. Also, the stock engine may have tighter clearances than my new engine? I trust your judgement, and if you say that 15lbs is safe, (hot and in gear) I will defer to your experience. (Just tell me one more time not to worry.) Like I said, I'm kinda anal. Thanks for all the patience. Regards, John.
Don't worry. Stock Buick bearing clearances are notoriously tight...if yours are opened up to the street/strip desirable 0.002" +, this is easily the reason for different idle pressures. At idle it's very easy for the pump to maintain the necessary oil wedge on the bearing surfaces. Since the rpm is so low, you don't have huge centripedal forces at the bearing journals trying to push the oil backwards through the feed holes. Also, since cylinder pressure is only enough to keep the pistons moving, there are no big loads pushing the crank down toward the main caps. This is why idle pressure is of such little consequence. Those two factors change as rpm and load increases, thus the need for the pressure increase as you go along. Your engine's cardiovascular system gets a clean bill of health. Devon P.S. If it just plain makes you feel better to go up a notch to something along the lines of 10W-40, it's not the end of the world either!
Thanks Devon. I feel much better already! Take care and have a great Fathers Day, if you are one. If not, have a great weekend anyway. Regards, John.:TU:
