3,000-4,000 mile oil change interval

[MrMPG]

I bought my 2022 mirage G4 brand new June 1st, I've done 3 oil changes in 7,000 miles using quality oils like Pennzoil ultra platinum, Amsoil and Royal Purple. So far Royal purple has felt the best out of the 3, Not a fan of mobile 1 (which is what my dealer uses) It's not even in the top 3 additive package wise when analyzed by Blackstone labs compared to others. My mirage is noticeably louder on the top end and rougher idling with the mobile 1 in it, Especially after a few thousand miles on that oil. I feel like a max of 5k intervals should be recommended for this engine for highway use and 3k for city with a 3-quart capacity, 7,500 miles is asking for excessive wear imo. I can feel the engine behaving slightly different after the 3,000-4000 mile mark. I'm very in tune to my cars, even the smallest things get noticed. My goal is to basically have zero varnish build up in the life of the engine. Even quality oils will leave varnish behind after 5k intervals, Im going the don't even give the oil a chance to get dirty route, A clean engine is an efficient/happy engine. Also going to be doing full AAMCO transmission services every 15-20k including pan drop, fluid exchange, primary filter cleaning and secondary filter changes. Most would consider it over servicing, I don't believe in such things i consider it protecting an investment for the next 10+ years lol, I paid a lot for the 2022 mirage, $16,500 base and about 18k out the door with a fully extended bumper to bumper warranty. Im going to get my money and milage out of it lol.

When Steve bought his "cheap plastic car" (2014 Mirage) several years ago, it came with free oil changes. Even though the Mitsubishi dealership went under, the owners honored the service through their Cadillac dealership. Steve received 50+ free oil changes (5W-30 conventional oil changed every 5,000 miles), & his engine was doing fine when he sold it after 307,000+ miles.

I agree that there is no reason to pay extra or less for Mobil 1 oil. If someone likes Mobil 1, however, I see nothing wrong with using it. If there is a bad full synthetic oil, I am not aware of it.

I think the key to Mirage long life is good maintenance, & I think your Mirage will have a good life!

If Steve's car did so well with 5W-30 conventional oil changed 5,000 miles, I figure a similar schedule with full synthetic oil should do just as well or better. Everyone has a different opinion on this, & it's hard to make bold claims without sending oil samples in to be tested. I am not interested in doing that myself, but I feel content with 5,000 mile oil change intervals for my driving conditions.

One of my cousins has a small town mechanic that claims synthetic blend is superior to full synthetic. His logic is solids in the oil drop to the bottom of the pan better. I don't really buy that. If nothing else, the solids suspended in full synthetic oil should be caught by a good quality oil filter. I just mention that, because people have different opinions when it comes to this stuff.

Pennzoil Ultra Platinum made the championship round of the Project Farm's test. The final clip below gives a great summary of the different oils. In the end, he uses Super Tech or Amazon Basics full synthetic. If you keep on top of your oil changes, I see no reason to pay a premium price for full synthetic oil. If someone likes premium brand name oils, there's nothing wrong with that, too.

At 5000 mi oci I think any api sn oil in an acceptable viscosity would get the engine to the 15 year 400k mile mark. I personally am liking the stats on the Valvoline extended protection synthetic. Your cvt regiment seems a bit excessive but not overly so considering reports of others on here. Your car will last as long as you want to keep it with your plan, provided you rust proof it too.

I dont personally think too much about maintenance but i feel if you changed the oil at even 2,000 Miles you'd notice a difference, whether that be placebo or not is for you to decide.

I do 5,000 mile oil change intervals with Mobil-1 and have had Blackstone oil analysis reports done 6 times over 100K miles (see this post).

My TBN numbers consistently show that my oil has plenty of life left in it at 5,000 miles. 7,500 miles would not be a problem. The only reason I do 5,000 miles is because it's easy for me to remember and I rotate my tires at the same time. From a purely financial standpoint, I am draining usable oil from my car at every oil change.

If you're concerned about how your oil is really doing, spend a couple of bucks and get an oil sample analyzed after you have racked up some miles.

Whatever you do, just keep good records and receipts so if something does blow up under warranty (not very likely in these cars), the dealer won't use "lack of maintenance" as an excuse.

This. These engines could do 9k mile oil changes, I'd venture.

Yeah, our highest mileage turd saw 12,000km(7500 mile) intervals for the first 300k km. Now it's done every 6000km/4000miles like the rest. It still runs. I want to do compression on it one of these days. It is a bit clacky when warm and occasionally uses 1/2 qt between changes. It's at 494k km(307k miles) right meow.

I change my oil twice a year in the turdmobile and ol' lady's dumpstermobile. The truck gets an oil change every other year or so? It's slightly overdue...

That's what I do too, every 12k km. I just feel like these basic ass engines can take a beating.

I don't understand how Royal Purple could have "felt" the best.

Engineers put a lot of effort into conception, design, development, testing, etc in order to publish the o.c.i. that they do. If you ask me, I'm betting even the engine engineers would admit that 7,500 miles on synthetic is conservative.

In any event, you can maintain your car how you see fit and there's nothing wrong with that. I will stick to what the engineers say and as a current engineer and former automotive engineer, I'm perfectly comfortable with that. I believe engine trouble due to lubrication issues is the least of my (or any of our) worries. Smartphones are much more likely to be the root cause of the discontinued usability of any my vehicles. Far far FAR beyond the risk of a lubrication issue.

I have done oil changes on my 2015 every 7500 miles since it was new. At 207,000 miles the engine is as clean as a whistle inside. Still runs like a top and has good compression. I used Mobil 1 almost exclusively for about the first 150k miles, but have since switched to Kirkland (Costco). The engine does consume a bit of oil, but that is to be expected on any engine over 200k.

Modern synthetic oil isn't like the dino-juice our dads and granddads used. Changing your oil as often as a conscientious car owner would change it in 1982 certainly can't do much harm, but it is kind of a waste. In fact, the OCI for the Mirage in Europe is 15,000 miles. Same engine. Why is it 7500 miles here in North America? Because the Europeans don't get the 10/100 powertrain warranty offered here. The point is these engines run clean enough and modern oil is good enough that those old super short OCIs simply aren't necessary anymore.

The 3A92 engines in the Mirage have proven to be very, very robust. In fact, they use them in ultralight aircraft. No need to treat it like a Ferrari V12.
