what weight oil do you run?

A 50w is WAY to much for an LS motor. The only thing you will gain is a loss of efficiency. A good 30wt is much better in these engines. Bumping up to a synthetic 40wt with no VII's or very little when running really high hp would be about as high as I would go. And contrary to popular belief heavy oils dont always protect better.

20w50 in my 427ci LS6, going on 8 years and 140,000+ miles.....still running like a champ. And its always been $2.49 Castrol GTX NON-synthetic regular off-the-shelf ****. Proof that the only thing that matters is keeping the oil clean and changing the filter every 3,000 miles.

Keep it clean....thats all there is to oil.

What dummy told you that nonsense???

Not in my case. Seems to be doing wonderfully. Especially since all my other friends with stroker motors over the past 8-10 years and their super-duper special synthetic oils and special weights......need engine rebuilds around 50,000 miles. lol

There is no magic oil but there is indeed a oil for every motor. Most engines get by just fine with convetional changed every 3k. Things change when you get into a high hp application. Regardless of oil needing a rebuild at 50k you arent telling us something. Lube related failures just don't really happen anymore. Its usually preceeded by someting else mechanical or environmental.
But if you want to keep your head in the sand and make uneducated comments on something you no little to nothing about, just keep on. For the sake of the other users here, I will call you out on misinformation every time. And dont respond until you educate yourself on the topic. I don't care about personal stories. Again, data is what counts. Motors aren't wearing out because of base oil choice. You aren't running an all out race motor.
LS6427-" Keep it clean....thats all there is to oil". Tell that to a tribologist and be prepared to get laughed at.

Pretty scientific response there. Most serious race teams happen to use synthetics FYI with very good results. You dont seem to know very much with respect to lubricants. I have been studying them for years. There is a reason for a 30wt being spec'd in a LS motor. You arent running a huge bearing clearance. Explain what you are gaining because you have zero data so your "worked for me" story means nothing.

For you to say that 50 weight is WAY too much for LSx engines is really a crazy statement, thats all. Its 100% false.
140,000+ miles on a stroker using regular old Castrol GTX, for 8 years and still going strong withnot so much as a hic-cup.......compared to dozens and dozens of friends and club members over the years with the same LSx stroker engines and they only last about 50,000 till they have noise, failures and need new rings and hones.
Pretty good 8 year test I would say. 50 weight is perfectly fine for any LSx engine, especially a regular old street/strip type LSx. These engines are nothing special, they are just engines.
I agree, if someone is building a high revving, solid roller, purpose built race engine....yeah, do what the builder says. But stock LSx's, 408's, 427's, 441's.....nothing special.

Honestly, who really cares about serious racing teams, there's none of them here. 99.99% of cars here are street cars.

I care about race teams because of your false statements regarding SYNTHETICS. Im tired of people here that dont even know what the "w" in oil means yet they like to share misinformation with the guys trying to learn. Synthetics have their place and will not wear our an engine when proper OCI and viscosity are followed. And your self test proves nothing. Any trended UOA's with particle counts. Detailed tear downs of several engines? Well then your study holds no water. It's not data.
You are right when you say an LS is nothing special. You need to realize with any engine a given or recommended viscosity should be followed. An LS motor is specd for a 30wt oil. As long as the oil used is a good 30wt then there should be zero issues. If the user wants to use a 40wt that is often allowed. When you start moving to twice the viscosity effeciency suffers and there is no gained benefit(ie wear). Your oil pump was not designed for a 50wt oil, neither were your small bearing clearances. Leave a 50wt for an all out race motor where clearances are large.
What oils are these friends of yours using? Brand and viscosity?

Amsoil 10-30 Synthetic ONLY. My engine was an oil burning POS until swapped to this oil. I have been to the drags twice and its still on full. I almost can't believe it. In my case took my engine a while to break in also.
