which oil filter, ac delco or mobil one???thanks....

I would go with the AC first, but I am sure that if Mobil ONE affixes their name to an oil filter, it can't be that bad for your car? Beside, I betcha somewhere on the box you will see the words about not voiding manufacturer's warranty or some such verbage?

I use the K&N (I think it is #1007 or something like that)

Mobil 1 for our two vettes...

I use the Wix filter on mine.

This is about the same as asking which wax is the best!

What does C5 Tech have to say?

Ive used AC Delco, Mobil 1, and the K&N filters and dont see any differences in them. You pay more for the Mobil 1 and K&N. Right now Im using an AC Delco.

I have used Mobil 1, DELCO Premium (UPF), and now WIX. WIX flows more than my UPF.

DELCO (regular) is really good enough.

WIX, NAPA Gold, Baldwin, or AMSOIL.

NAPA Gold here. Made by WIX. Don't forget to torque the filter down, 22 FT-Lbs for a '99.

..one of the best- filtering AND flowing filters out there!

That's the one I use.

I have 34k on my car and have only used the AC Delco filter. I have had no trouble with filter or oil.

I do torque mine, but I would like someone to tell me what it is so high?
It is about 2.5 turns past contact !

I use Fram. When you go tighten it down. Turn it by hand unit it is tight, then turn it @ 1/4 to 1/2 a turn more. You really don't need to torque it down. Just make sure that the gasket from the old filter is actually off and not stuck up onto where your new filter and gasket is to go. You will have problems if this occurs. I really don't think it really matters on which filter is used. It's just an individual preference. Spend $3 or spend $15. Whatever floats your boat!!!!!!

I'm a big fan of the Wix filters myself. For years I was running the K&N oil filters on both of my cars, and they are great filters, but pricey and hard to find for a lot of people. I decided to give Wix a try and they've worked out well for me, my oil analysis results have shown they work just as well as the K&N, but at a lower price.

I know the Wix filters flow very well, plus they are constructed very well also. They use a T3 semi synthetic media and a silicone antidrainback valve (which is more durable in extreme heat/cold than nitrile, which is what a lot of oil filters use)

If it is not used for track days stick to AC/Delco 6 for $54 delivered from GMpartshouse.com
If you want more flow go to K&N at about 1.5 x the price.

While doing some filter research, I found some reviews on many filters. It seems that the Mobil 1 and K&N filters are identical, except for the filtering media. The Mobil 1 uses a synthetic coated media. Other than that, they are the same. Ones recommended to stay away from are Bosch and Fram. Purolator and Wix were good along with the NAPA Gold. Lots of info at www.bobistheoilguy.com. Read some of the forum comments. Good luck.

K&N only!

Next question should be: What kind of oil?

Administrators will love that.

At least we will give them something to do!!

They love closing threads. I think I am in trouble.
