Re: What weight of oil are you using. 10-30 redline year round.
as long as we are on the subjet of oils, patman, what do you feel is the criteria for oil changes. time or miles?
when I used dino oil, time was more relevent. 90 days was the longest I would let oil stay in an engine even if I only drove it to the beer store and back once. I was taught that the byproducts of combustion would break down the oil in this amount of time to the point that damage would result to bearings, seals, gaskets, etc.
what I understand about synthetic oils is that these rules do not apply any longer. so, short of doing an oil analysis, what rule of thumb applies? and where would one send oil to do an analysis if one were so inclined?

Re: What weight of oil are you using. If you're interested in oil analysis, click here for info:
http://www.bobistheoilguy.com/oilanalysis.html
When using synthetics you can safely go one year on it, so don't change it out after 90 days if you've only got 1000 miles on it for instance. Many guys on the oil message board go one year between changes with excellent oil analysis results. If you go through a harsh winter's worth of driving, definitely change the oil when winter is over though. But you could then go the rest of the year on one oil change if your mileage isn't too high. I wouldn't recommend going over about 8-10k on an oil change without oil analysis.

Re: What weight of oil are you using. IS GTX a fully synthetic oil?
If a non-synthetic oil is changed frequently (...say every 3K miles), and the expected useage over the life of the engine is about 100K miles, then what is the advantage of using a synthetic (besides making Saddam rich) over a good DINO?

Re: What weight of oil are you using. GTX is not a full synthetic, but it does show good oil analysis results, in fact the best oil analysis I've seen so far in an LS1 has been with 10w40 GTX. I would like to see a lot more LS1 guys doing oil analysis though, to really get a bigger data point to see what oils work the best. My oil analysis consultant really likes Redline in the LS1 from the results he's interpreted for customers.
Synthetics are superior when it comes to cold flow, so if you run dino oil in a cold winter you will definitely reduce your engine life. I also believe that under very high stress you're better off with synthetics too, especially if your engine overheats for instance.
And when it comes to running 5w30 oils, conventionals simply thin out too much, while good 5w30 synthetics don't.
There is also the major benefit of being able to go longer between oil changes with synthetics. I know many of you will stick with 3k intervals no matter what I tell you, but with the information I've seen you can easily go 6k with a good synthetic oil. I change oil on 4 cars in my family, so I don't want to change them all every 3k! In my sister's car for instance, she drives 500 miles a week and will be driving even more in a week when she moves further from work. So I'm going to be running 9-12k intervals for her car.
With all that I've said above though, if you already only plan on keeping your car for 100k, any oil will get you to that point.

Re: What weight of oil are you using. The new NASCAR rules do not permit you to use a differnt engine (or different oil) for qualifying than you use in the race....
...under the new rules, effective this year, you start at the rear if you change engines between qualifying and the race start...
Hey Patman:
You work (or own shares in) Redline Oil, right?
Does anyone know if the top fuel racers (Nitro 1/4 mile drags) use oil with short-duration additives...the oil looks different from the oil that I use in my street car...if yes, these additives only need to last about 4.6 seconds...

Re: What weight of oil are you using. Patman:
OK, thanx. It is really not that I indend to only keep the car 100K miles. It is more of a case of having the engine installed in a Chevy car that is the limiting factor....
As you know, after that period of time, bad stuff begins to happen, like:
Your rear view mirror falls off in your hand...The windows fail to open and close
The breaks start to fail...The car leaves a puddle of Mobil One on your driveway...The A/C stops working on the hottest day of the year....
The trunk leaks and ruins your luggage...
And on, and on, and on...
My point is that your engine only needs to last until the rest of the car is junk. With a GM car this is before you hit the 100K mile mark.
Knowing this, maybe it best to save your money and never change oil.

Re: What weight of oil are you using. In the old days, Quaker State oil had a very green tint to it. It was supposed to be excellent for wear protection in engines.... it was drawn from oil wells in Pensylvania...
Did any one ever do a test on this oil and compare it to modern synthetics?
...the green goo stopped pooring from the Quaker State cans (no plastic bottles then) about the same time Alnold Palmer (a Pennsylvania native and advertising sponsor) stopped being competitive on the PGA tour...
A real shame ...considering the green goo was then only .37 per quart. In inflation adjusted dollars, that would put it about only $2 a quart!!!

i was running valvoline synpower 5w30 and it always seemed to run awesome but the local parts store was running a sale on Castrol Syn Tec 5W50 and i figured since it was summer what the hell ill give some thicker stuff a shot.\
Any opinions on the Castrol Syn Tec?

O and I would never use a 50 weight oil for a motor design for 30 weight. 50 weight pumpabilty goes down so parts dont get lubercated properly on time and oil temps go up.
