I know my engine sounds better... but the old oil was probably crapo when it was put in. I've used strictly Mobile 1 Extended oil and filters in my last 3 cars. The walmart near my house just started carrying 5w-20 extended in the 5 qt bottles. It saved at least $7 on cost.
I'm not the OP, but they have good prices. $10.99 is pretty good.the website the OP linked has flat rate shipping, so i bought 3.
K&N is the same as Mobile 1, but these are "extended performance". They claim to have twice the storage for trapping contaminants.I was using motorcraft or K&N(usually can be got cheap on amazon) filters and Mobil1
I'll never get that bored. lolthey do... cut one apart when you're bored.
I read somewhere - may have even been in the manual that full synthetic is not recommended for the LS, instead sythetic blend is. I'm sure someone else can/will provide more detail.
Before I was laid off, I was doing my changes at 3,000 miles... The old fashion recommendation. I've been using Mobile 1 Extended Performance and their extended capacity filters since 2004. It's better protection, and will likely go much further than 3000 miles, but I wouldn't go 15k. A lot depends on your environment, how you drive, and the type of driving you do (city vs hwy). Every 6~7,000 seems like a good time to change it to me. Oil & Filter every time.Ive never gone full synthetic before, but i read you can change oil at 10k but should change filters every 5k. any suggestions? I know the mobile 1 oil says it will protect up to 15k, just trying to see whats reasonable.
This article is a few years old but it is a good overview of oil filters and whats inside them along with who makes them.

Well my mechanic suggested i add some rislone motor treatment and run it for a day. Then do a oil change with some house-brand oil and new filter, run it for a day or so, then switch to the synthetic oil and a good filter.
I did the rislone yesterday, and he changed out my old oil today. Tomorrow he'll drain it out for me and put the synthetic in.
But yeah i searched for some oil threads and it seems like a tired debate on blend vs full synthetic.
