Synthetic vs conventional
Well i did some research and its hard for me to believe some of this stuff but it looks like im switching to Mobil 1 0w30 or 0w40 b/c this article

And here it says that you can switch between synthetic and conventional, it calls it a myth

it probably is technically but i personally wouldn't dare putting conventional back in after running it for so many miles with superior oil. why downgrade? if you can't afford to continue using synthetic, then,..... i dunno you got probs
That article raised a good point i never thought about, they have blended syntec and what not that the factory makes. Also it said that the reasoning behind not being able to switch has to do with synthetic doing something to the seals, cant remember and dont feel like looking. but i agree it would be a step backwards but if thats a reason your not going syn then problem solved
Hey Quick, I use Mobil 1 because that's what my car has always had in it. Do you change your oil every 3K? You heard what Venom had to say about Havoline. Conventional oil will do a fine job for you, use what you have now and a good filter. Unless you want to baby your ride and feed it the expensive stuff for your piece of mind.
I drive mine < 10K a year so that's 3 maybe 4 changes. I'll spend the extra bucks for synth and a K&N filter. Check out Walmart, I think they had Mobil 1, 1 gal for $21. Add another qt and a SuperTech filter and your still under 30 bucks for an oil change.

I was checking about syn. to conv. since I have never used syn. in my life and see that alot of peeps do so I wanted to hear their take on it.
But I am still in debation mode right now about which way to go.
I just changed the oil but the time will come again really quick since race season is upon us.
But I really appreciate everyones response on why and why not they do or dont use syn.
I am reading this stuff about it and that will persuade me yea or nea.
well it will give me more of an insight as to benefits and what not.
The only benefit you'll really get from synth is a longer oil change interval, but you're still supposed to change your filter every 3-5k miles.
Personally, I run conventional in my SS (w/a prefernce to Valvoline) and I ran it in all my cars prior. I noticed that I'll use at least a quart in 3k miles w/ mobile 1. With other synth it is a little less, but I still use oil. With conventional, I don't use any to very little. change every 3-5k miles and you'll be fine.
My wifes 01 Grand am GT had 175k miles on it w/mostly conventional and it still runs like new and now my sister-in-law is driving the **** out of it. I have friends with a 180k+ and a 200k+ truck that only runs conventional oil and these are farm trucks so they see towing, and long idle times etc. If you care to do a search there is a pickup that got a million miles running only conventional oil. Its a Chevy BTW.
Now the TBSS, I may stick w/synth. I'm up in the air about it.
IMO, filter choice is where the debate should be and its hard to beat a Wix, but I'll run AC or Supertech also.
If anyone cares the Supertech oil is Quaker State so you can get QS synth pretty cheap that way.
if your changing your oil that often just go with the cheap conv, if you dont change it as much then id say syn, in my eyes i just feel better knowing im putting the best oil in it, but seriously if you change it that often it wont make any difference, i agree its more about the filter. Ive heard that syn isnt as good in higher mileage vehicles sometimes because it can leak through any small gasket weakness, and conv wont do that, cant remember where that was though

Verdad Gallardo I've gone back and forth on several car and never had an issue. What do you think synth blends are?

I look at oils like gasoline. Conventional oil is compared to 87 octane. Blends can be compared to plus gas, 89 octane. And synthetic is the 93 octane. It's more what you can afford vs. quality imo
While we're on the topic, I'm bringing up a thread I posted a few weeks back since no one really cared to respond: https://ls1tech.com/forums/general-maintenance-repairs/862175-synthetic-blend-oil.html
If I'm running a high mileage LS1, will full synthetic really encourage leaks?

It makes since to me that it would, think about it this way. Synthetic means man made, basically they took small molecules and added them together to get the wanted effect. Now the syn molecules i believe are smaller then the naturally occuring thus increasing lubrication and what have you. Also its pure, in conventional oil you have sulphur, and other elements that wont be in the syn. This is just my thinking on this so dont quote me but it makes sense. If you dont have any leaks i wouldnt worry about it until they show up, think of it as an advanced warning lol
