+1 on using full synthetic and changing ever 3K miles. Some people say you can go longer but I guess old habits die hard.

i'm gonna start using a 50-50 blend.

Is there any disadvantage/harm in using a plain AC Delco filter designated for my car? Or are there better options to go with if I run Mobil 1 full synthetic 10W30?

And should I bother with an oil additive? If so, which and why?

I don’t know of you realized this was a thread from 2010? You might get more responses starting a new one.

Last question first, I don’t believe in additives. Maybe decades ago, but modern oils have everything needed in the bottle.

For a well aged engine, the one thing I would NOT do is long intervals between oil changes. Because as rings wear etc. you’re getting higher levels of contamination than in a fresher engine. So change oil frequently is the main thing. Better to use Walmart Supertech at 3k miles than buy expensive name brands and eke out extended oil changes. No matter what oil used, it can only suspend a certain amount of contamination, and once that’s exceeded, you’ll be depositing sludge in the engine.

Filters are always an interesting topic, many brand names are sold out of a relatively few factories. My .02 is as long as you’re not buying the cheapest 2$ filters on sale then the middle tier are all quite good. Nothing wrong with AC Delco. And probably little to no benefit from more expensive options.

I did realize that, and I'll probably make a new one I just wanted to give this thread a refresh. I've heard that as well, and it's not been very long since my last oil change but I think its time. I'll probably just stick with AC Delco, its been working for me so far.

What if I told you it doesn't matter

I use Pennzoil 5W30, and Fram filters. The 5L jug comes on sale every couple weeks, and I pick up 2 when I am about to do an oil change. I have to replace the oil pan gasket, so I don’t have to keep adding so much between changes.
