What oil and filter for my 03 purchase. I know this is controversial. I'm guessing mobil1 synthetic but what filter and where to purchase

vettenuts

You will get a number of oil recommendations so I won't bother (I don't use Mobil-1 ).

As for the filter, you can't go wrong with AC or WIX.

The info for the oil is on the oil fill cap and in your manual. Filter, take a pick...........................

napa gold or wix filter mobil or amsoil

My first oil change is coming up soon and my 98 came with enough mobile 1 to do it but I was told Royal Purple is better.

ALLEGRO

Any of the fully synthetic oils meeting the GM standard will perform just fine. I recommend the GM filter, but again, most "top shelf" units from the major brands will serve well.

I've ran ACDelco, WIX, NAPA Gold, Amsoil and currently a Purolator PureOne PL14006. All give me the same oil pressure, so all flow well.

PureOne probably has the best filtering efficiency (99.9% @ 20 microns), and they flow very well as can be seen in lab test data. Hard to refute real test data, which is hard to get from the manufactures like shown in the link below.

Synthetic and good filter.not fram

joe Villarreal

ac delco is a good filter

printmanjackson

do these filters have a bypass valve built in?

I remember on the old school generation engines we use to address this valve on the filter adapter so it wouldn't open so easy and it would filter all the oil.

go by the manual.
fill cap is just an advertisement. they could have put pennzoil platinum on the cap just as easily. any GM specd oil. there is a list floating around here.

get the oil I use!

I use Mobil 1 and the K & N oil filter. I've forgotten the part number for the filter.

Mobil one is my choice---I'm not a fan of the over advertised Royal Purple its a reatil brand
Also Mobil One now has several choices--be careful here they have
Mobil One Super Synthetic
" " Hi Mileage
" " 4x4 truck
" " Extended Performanace
and 2-3 others---
The super synthetic is the cheapest at around $4.99 QT
The Best is their Extended Perf. at around $8.99 qt
As far as filter go---I have had bad lick with Fram--plugging up and also lowering oil pressure---even when NEW----A test was dome I found online---Not done by a Manufacturer and they found that the Best filters that flowd the best and cleaned the best were :
1. K&N
2. Mobil one
3. A/C Delco
ALSO---For even better protection you can install a filter than is exactly the same but 1" longer---I use this-No ground clearance issues and my caris lowered with LT's- It is the filter used on GM truck 6.0 engines---I think the K&N $ is 2006

And then some you never thought to ask...

For a street driven Vette, my suggestion:
AMSOIL Signature Series 100% Synthetic 5w30 (Product Code ASLQT)
AMSOIL Ea Oil Filter (C5 uses EA15K32)

Kehraus

I use Mobil1 synthetic and Mobile1 oil filters.

They had a special at AutoZone for the 5 1/2 qt size and the filter for $33.
