Not at startup but when it is at running temps. Do YOU realize I have had this car since it was new and when I hear more noise BECAUSE OF THIS OIL makes me not want to use the oil again. I NEVER used 30 wt M1, I have no idea where you pulled that out of.
and don't talk down to me like you are some kind of God or something

i'm not talking anyone down. i'm just simply stating that an increase in valvetrain noise on an engine historically known to have a loud valvetrain doesn't mean it's wearing more. most people "hear" that their engine is louder when switching oil because they're actually listening for it. get your oil analyzed before you jump to any conclusions. my guess is you're getting so defensive because you know you're grossly overreacting.

Whatever . I have listened to my engine since 2001 when I bought the car. I have been on these boards faithfully for years, I just don't post much. Then I do post and get this uneducated banter from you? Where do you come up with this crap? Stop assuming what I do, it is very ignorant to state what you think somebody else is doing when you haven't a clue

anyone try that mobil one extended performance?

so...my post is uneducated, yet you're making conclusions based on nothing. do you see the irony here? i'm telling you to get a UOA before you count any oil out so you can make an educated guess. you're basing your opinion off valvetrain noise on a car with a historically loud valvetrain. you're the one making uneducated banter. you wanna find out what oil is best for you? TEST IT. don't assume - which is also ironic, since your decisions are assumptions.

so, in short, you're the one making uneducated decisions and you're the one assuming. does that make you a hypocrite? get it tested. i'm doing my next batch of GC

I am changing oils. I will go back to M1 0W40 in which I have used since I bought the car. You can use whatever you want but don't read a post and jump to a conclusion of what weight of oil they are using, they are imagining the increase in noise and all the other drivel you have spewed in this thread.

i never said you were using a 30 weight mobil 1 oil. i said i hope you aren't, as it would be a huge mistake to go from GC to one of the worst synthetics you can put in your engine. mobil 1 0W-40 is better than their 30 weights. however, 5W-40 for turbo diesel's is even better. i'm going to run that the next oil change. the mobil 1 5W-40 is about half the weight of GC 0W-30 though. i picked up a quart of GC and compared it to the mobil 1. the mobil 1 is so much lighter. not sure how good that is. we'll find out - i'm getting them both analyzed. i suggest you do the same for the GC. GC sometimes makes more noise because it's such a heavy oil, but it shows EXCELLENT wear results. sometimes extra valvetrain noise is worth it if the wear numbers improve. you need to understand this.

im running castol syntec 5w-40. its pretty damn good. i just wanted to say thanks to patman for recommending it. i havent had any oil consumption at all. i tried to add oil a week ago, and the $hit was still full... so i blew 6 bucks for nothing..lol.

I live in new england what would be a good choice for me in the summer and winters and a good oil that will quiet down that ticking sound that ls1's are known for.

I've come to the conclusion that using synthetic oil is, well, BS. Its a way to get more money for a different type of oil. I have about 75,000 miles on my 436ci stroker, using basic non-synthetic oil. My engine has all its original parts and the oil pressure is still close to 60 psi on cold start-up and no matter how much driving I do, aggressive or casual, without A/C it NEVER falls below 42 psi. The only way it will go below 42 psi is if I'm sitting in 95* weather down here in Florida in stop and go traffic for an hour. And then it'll only go down to about 35 psi. The engine runs 100% free of ticking, slapping or any kind of irritating noises too.

Synthetic oil is a waste of money IMO, and my opinion comes with a very high mileage stroker engine to back it up that still runs like the day I first started it up. The oil I burn is normal and has to do with my stroke length and ring set, has nothing to do with the oil used.
