Next oil change due never. It uses so much oil now that I just add it as needed. Filter change due meh whenever I get the chance. Cars junk. No need to spend a pile of dough on it. Just get the cheapest stuff on sale.
Normally for conventionals I'll run
-Formula Shell and cheapest filter I can find for old beaters. Something like my buddies 98 Escort with 300K, or his 97 Dodge with a ga zillion city miles fits that bill.
$10 for 5 quart jug...cant beat it.
Next I want to try Tractor Supply Co brand
-Castrol GTX and a Napa Gold/Wix for a good conventional
My dad swore by this oil every 3K
Normally for synthetics;
-O Reilly Full Synthetic and Wix/Napa Gold Or KN Silver PS
I like using on a budget.
-Castrol Edge and a Napa Platinum or KN Gold
I like using when I do a lot of highway driving.
-Royal Purple and above filter
I like using when I drive down dirt roads daily. Keeps my engine spotless for the first 3k I use it. It's amazing the stresses mountain driving puts on a vehicle.
^^^That's my personal oil hierarchy^^^
