I don't have a racepak in my car...I use a in car video camera to watch gauges through out the run....poor mans recorder..lol I use the 191 Schaffers 20w50 in my 421 SBC with a moroso billet pump. basically 40 lbs at idle and 80 down the track. car runs 5.50's at 2450 lbs, so its pretty sporty for a 23* small block. | |||

I don't know what Steve does, perhaps he'll answer later. It's not necessary to boil it out though. The reason oil get's milky when there's alky/condensation in it is because alky and oil won't mix. Left alone the oil and alky will separate. Let the car sit for a day or 2 then just crack the drain plug and drain out the moisture/alky. It's heaver than oil so most of it will go to the bottom of the pan. The alky/water will come out first. As soon as it turns oily stick the drain plug back in. To get rid of the moisture/alky milk that in the valve covers just take the breathers out and leave it open in the trailer after the race. The bad stuff will evaporate. This may not work as good in some climates though. I ran alky forever, even in extremely cold weather winter time races. During the winter I'd drain the oil and sit the drain pan next the my heater. It would be clean in a day or so. I only done this when it was really cold. I used to be a people person, but people ruined that. | |||

Never had an issue with Schaeffers 40wt Micron Moly in our 565. Oil pressure steady as the day it was on the dyno, four years ago. Sample every oil change, just getting better and better. Going about 40-50 runs with alky carb. Tried about every other brand. All are actually pretty good but the tests just show the additive package and very little foreign metals with Schaeffers is the best we tried. Granted I did not try $15.00 per quart Redline or some of the exotic oils. | |||

There is something else wrong. Switching brands had nothing to do with it, Maybe air was in the oil pressure lines or a small piece of debri stuck some where. | |||

Methinks maybe Footloose is correct. Clowns to the left of me, Jokers to the right. Here I am....... | |||

I’ve ran Schaffer’s for years now but have also ran Brad Penn and Lucas in the past my racepak never seen much change on oil side. It does look typical to what you would see with low oil level. David Lanning Lanning Electric Team Mickey Thompson | |||

Maybe his oil pressure issue was more than just what oil he was running.... Was watching D1TV yesterday and he blew it up pretty bad on a time run.....have no idea what broke....I'm not there... | |||

kicked a rod...got greedy 89 passes on aluminum rods...thanks for reminding me | |||

Sorry for your misfortune, I was watching the race live.... You were discussing this very thing earlier this year I think about those rods.. Hopefully it didn't trash the block and heads... | |||

Man that both sucks and makes me nervous. I sent mine back to MGP to be checked in the off season at 35 runs, they said they looked perfect and could safely run them the rest of the season and get 100 runs on them. Currently have 74. Pan is off right now, I am going to change rod bearings just because it makes me feel better. | |||

Ouch, sorry to hear that.

Did you collect oil pan temperature? Like most have said, Shaffer’s oil is an unsurpassed value and being a paraffin based stock, the micron molly is a wise choice for methanol combustion. Also unrelated, using a multi-grade race oil is a mistake. It uses additives that will cause it to shear quickly out of grade. Depending on clearances, pick a straight weight oil and get into a routine of carefully warming the oil be putting the spurs to it. An oil temperature gauge is your friend. Send a virgin sample of each oil to a reputable lab and you’ll have the information you’ll never find here on the oil you claim acted differently. Data talks and BS walks is a good moto. That is an less then $100 investment. In addition, call Shaffer’s oil and share this. They are a small oil company that prides itself on proper customer support. Your message here deserves giving them a chance to defend this disparaging report. 2005 2000lb 4 link dragster home brew 582 BBC Dart 355 1.058 2.98 4.629@149 6.094 7.310@185 | |||

At this HP level I think of inspecting the rod bearings and replacing them before they fail is on the same level as replacing aluminum rods before they break. Just preventive maintenance, upon inspection what if I find a bearing that's starting to fail, maybe its beat flat because the rod is out of round.....I may have just prevented a blown up engine IMO rods dont break on their own, a bearing, bolt or wrist pin failure usually prempts the rod breaking. | |||

I check and replace bearings frequently. I can read a tuneup by the bearings. I’ve added fuel to clean up a plug, but then found i needed to add more fuel to keep the bearing happy over a ~10 run cycle. MGP sees a lot of rods and has good data. I put about 105 on my last set. They were inspected somewhere in the middle and I was told 100-120 (more or less, they were mildly non-committal). I would have gone a little longer but a pin moved in one of the rod caps so I decided it was time. On blown alcohol to me it seems crazy to not check bearings for squish and tension and replace as needed. I’ve never gone more than 20-30 runs without seeing at least one bearing I wanted to replace. If it’s a 4.40 bracket car, maybe not, but if you’re burning any cad at all, checking bearings is easy insurance. | |||

...........I' m with ya on the Red Line race oil. Been running it for years. We currently run it in three blown cars and wouldn't run anything else even if it was free.

you guys keep thinking there is magic in that oil? Clearly, from the graph, it's 1-2 quarts short of making the stripe.(just like Mike ;]) 6.41@221 (so far) 4.11@178 off the shelf/built it myself | |||
