A couple weeks ago I switched from castrol gtx to amsoil, both 10w-30. I had very little if any piston slap or any other noise from my ls1. After switching to amsoil there is a very noticeable noise coming from the engine. The only reason I switched was because of everyone saying gtx creates a...

Has anyone used this over a long period of time in their car and if so, any problems? I thinking about using either redline or amsoil in my trans am and was looking some opinions from people who have used it more than 1 or 2 oil changes.

I am going to start using redline 10w-30 on my next oil change. Now I store the car from Nov.-April. Could I get away with just 1 oil change a year. Change it before storage, run it during the summer and then change again before storage the next winter? Car is not a daily driver and only gets...

Does anyone have one that they can post or know where it is on there website, I can't find it on their site.

Ok, it is time to bring my trans am out of storage for the winter. Currently all i have run in it is castrol gtx. I thought about royal purple, but was skeptical about it and after seeing Patman's oil analysis, I don't think I want that in my LS1. So would you stick with the castrol gtx or make...

Do oil filters have a shelf life? I purchased about 8 of the ac ultraguard oil filters for my ls1 when the word came out they were being discontinued, how long will they last?

I am looking for what oil to use to maybe help cut down on an oil leak. The car has the gm 3.8 v6 in it and I guess it is notorious for rear main seal leaks. It was fixed once around 25,000 miles and it may be leaking again as there are a couple drops on the ground, nothing like it was leaking...

Just wondering if you guys think it is thin compared other oils. Looking to switch from castrol gtx to mobil 1, but worried about it being too thin, especially with the ls1, which likes to drink oil? From what I have read the ss is better than the tri-syn mobil 1?

Long time lurker here, been reading for some time here after I saw patman's suggestion to this site from a post on ls1.com. Anyway, here is my question. I have a trans am with an ls1 engine. Currently I use gtx dino oil in it. The car is a weekend car and is stored about 4 months during the...
