Just did my first UOA. Couldn't be happier with this. 2004 GMC Sierra - 5.3. Mobil 1 5w30 ever since the second oil change at ~1500 miles. OCI has probably averaged 5-7k during that time. 230,000 miles strong - operates just as she did on Day 1.

Very very nice, The new formula (add-pack) seems to be a winner. Good filtration too.

Very low wear numbers for that motor. Thinning a bit.

Your UOA and description gives me motovation to continue with regular maintenance. The payoff is a great running vehicle that you can be proud of.

Another good UOA on the 5.3. Great truck, great engine. How far can you extend it?

I'm going to be a bit blunt; not meant to offend, but rather to give you an honest assessment of your maintenance plan. A bit of "tough love" that may hurt to hear now, but will be an asset to you later on.


M1 for 5k miles is total waste of money in this application. Any decent house brand dino fluid can do this well. Seriously; dino oil would do every bit as well here. Your wear rates are totally average, and you paid probably 2x more money for M1 than any decent house brand lube that will protect every bit as well.

Certainly the engine and lube are in fine shape; that's not the point. The underlying issue here is paying a premium for performance that is every-day average.

If you want to get the value out of your lube, then you'll need to greatly extend the OCI.
Or ...
If you intend to stick to 5-7k miles, then run any recognized house brand conventional oil and any decent normal filter. And quit the UOAs; there is no logic to paying for information you promptly ignore.

The act of preventative maintenance, in and of itself, is FAR MORE important than brand/grade/base choices among lubes and filters.
- under maintaining something is akin to abuse/neglect; that can kill equipment by shortening the lifespan
- over maintaining something has never been proven to be anything but a waste of time and money

Good to see you actually stick to one oil and not skip around like most do. The results you have with continued use of M1 is typical for all of us that use M1. I have several friends and family that only use M1 oils and all of us have the same result as yours. Very long lasting, clean, and excellant running engines. My only suggestion would be to run your OCI out to at least 10K. A friend has the same engine as yours and does 15-20K OCI and has 350K on his engine and it still runs great and remains clean with no real oil use.

Probably 75% of the time I've used AC Delco filters. 5% FRAM when in a pinch and the store was out of AC Delco. 20% of the time I've purchased m1/Bosch filters if there was a good sale.

I have never investigated the filters inside to be honest, but since you mentioned that I did some searching and read that the ACDelco filters with an "E" at the end of the part number are the encore. I have noticed a few of those more recently, but never paid attention. I figured the E was for something like "extended" or "enhanced". Doh.

Thanks all for the feedback and opinions. My OCI is probably closer to 8k now, the 5-7k was an average over the previous 200K miles. It was 5K for the first 100K miles, and I've slowly extended it since then.

I don't disagree with the facts, but even if Blackstone Labs gave me hard proof with an engine warranty that I could switch to a 12K OCI I wouldn't do it at this point. Like the guy who scoops up every last bottle of Motor Honey when it goes on sale, I'm sticking with what works for me. That's M1 every ~8K miles, tranny flush every 25K, and everything else I take the manufacturer recommendation and cut it in half. Seafoam it twice a year thru the brake booster hose and throw in a bottle of fuel system cleaner every 3-5K miles. I had the intake manifold and injectors off not too long ago to replace a knock sensor....clean as a whistle. Not a single drip of fluid has ever leaked from this truck except the front diff (axle seals). 230K on the original 4L60E tranny is way above normal. No water pumps replaced, no power steering pump failures, nothing, nadda, zilch.

So I may be throwing money away changing my fluids too often....oh well.
