k guys i purchased my car about 3 months ago and the previous owner had the oil changed at his local lube place with dino 10w 30. so it was time to change oil so i changed it with mobil 1 high mileage 10w 30 and as soon as i got done and fired it up let i run for a few minutes then i noticed a faint ticking that wasnt there before? but its only in between 1000 and 1800 rpm's it has the sewing machine sound? so i did some searching on here for oil and decided mobil wansnt the best oil for my car i have 91k by the way, so i changed it to a 5w 40 today hoping that that would cure the issue, so when i got it changed and started it up same damn thing! it seems to be just a tiny bit quieter but still there. so just wondering if anybody has any input on my issue here? it kind of gets a tiny bit better after it warms up but still doesnt go away. oh and it is really noticable when it is on the downside of the rpm drop. it is definetly coming from the passenger side in the rear.
my oil pressure is about 45psi at idle and about 55- 60 psi at cruising speed.
thanks in advance guys!

Perhaps the previous owner had some kind of additive, or heavier weight oil, to suppress the typical LS1 noise for the next buyer, and didn't mention it.

ya maybe? it had the sticker in the window from the lube place and it said 10w 30 on it?
maybe ill put some lucas or something in it and see if it quiets it up?

After looking at bobistheoilguy.com I wouldn't add anything to my oil.

Maybe mobil1 and your motor just aren't as happy with each other. Could try another brand maybe. I've been hearing good stuff about pennzoil platinum

where is everybody getting there Amsoil?

The ticking is not uncommon in the LS1, and isn't causing any damage.

5w-30 is what GM recommends for the LS1. Additives are not recommended, as they are usually just thickeners. Those that don't thicken are usually snake oil.

Mine sometimes seems like it has a very faint ticking, seems normal to me, like from the valve train

its wierd though it only ticks at about 1100 rpm's to 1700 rpm's kind of wierd. oh well i guess its probably normal? im just kind of **** about every little noise i guess i just need to turn up my radio

A long time ago I went from a CB1100F to an '85 Electraglide. The noises were completely different. I thought the Harley was going to fly apart right underneath me!

But it didn't.

You just have to understand what the noises are an get used to each set.
