It's fine it can happen but they shouldn't fight you when it does.
0W20 and 5W30 are both fine, no harm done there. Under normal driving, the 30 weight isn't "helping" but it's certainly not hurting either. No biggie.2017 Premium

Having to add coolant daily. 1 bad missfire with blinking CE light for about 30 seconds but never happened before or after that day. Drove fine right after, was out of town had no choice but to drive it back the rest of the way home.
Water pump replaced Yes
Both turbos replaced Yes
Not sure if spark plugs were replaced doesn't say on the invoice for some reason.

Been using 5w30 instead of 0w20 since I bought it less than 9 months ago (about 2 oil changes) thinking it would be better for the engine was I wrong?
How soon should an oil change be done after an engine replacement if anybody knows. Service rep said normal 5k but that doesn't sound good given the circumstances.
Thanks, will probably be moving back to 0w20 as I've read about people getting their claims denied for much less. Definitely will have to change the oil soon for the peace of mind. Just surprises me they advised me not to no sooner than 5k.0W20 and 5W30 are both fine, no harm done there. Under normal driving, the 30 weight isn't "helping" but it's certainly not hurting either.

For fresh engines, I change the oil right away, then change it again after 1,000-2,000 miles to get the assembly lube and break in particles out of the oil and filter. After that, 5,000 mile intervals are kind of the accepted norm.
Yes, I considered getting one before I even had Infiniti determine I had a blown head gasket. It'll be interesting to see what the results are on a fresh engine.^this & consider sending an oil sample to Blackstone for analysis
That is why I am reluctantly using 0w20.Thanks, will probably be moving back to 0w20 as I've read about people getting their claims denied for much less. Definitely will have to change the oil soon for the peace of mind. Just surprises me they advised me not to no sooner than 5k.
The results will probably show higher iron, aluminium, silica, and moly because it's a fresh engine. It's not going to be alarmingly high, just a bit higher one the first oil change. Then, a little less each time until 2-3 changes down the road.Yes, I considered getting one before I even had Infiniti determine I had a blown head gasket.

If possible, keep an eye on oil temps. So long as they're under 240 degrees, there's nothing to worry about.That is why I am reluctantly using 0w20.
I have an extended warranty and intend it use it if needed.
all oil changes are now done at the dealer.
I have no way to keep an eye on oil temps. I could in my 2015 WRX though.If possible, keep an eye on oil temps. So long as they're under 240 degrees, there's nothing to worry about.
Though a 20w is less viscous than a 30w, it has more than enough film strength at normal heat ranges. A cooler 20w can/will be thicker than a hotter 30w depending on the temperature delta between them.
What were your symptoms when you took it in? Also can you or others post your price, so those of us that are modded, or out of warranty stand to know what replacement cost is at the dealer.2016 Infiniti Q50 Premium AWD

Had to refill engine coolant every other day.
I want to say the problem may have been getting worse as time went by since I did notice small amount of coolant missing every month in 2021(didnt go below min. mark, but I know coolant level shouldnt be going down at all unless there's an issue), no leaks, pressure tests conducted 2 times that year, all passed, no white smoke, oil analysis done in July of 2021, negative for coolant in oil.
May('22), loosing coolant every other day. did an oil change, noticed oil was creamy, white cream built on the filler cap, sent sample of oil for analysis. Car didn't overheat, but fans kicked on more frequently, brought into dealership beginning of June for diagnosing.
Sadly, I had over 75k miles at this time, but had warranty with a company, which did make things difficult. After 2 inspectors and inspections by different Infiniti techs, it was determined that I had a porous block & bad turbos...engine internals and block had no cracks/signs of extreme wear, no metal shavings, etc. Oil analysis came back positive of coolant mixed in.
Total bill came to 32k (long block, turbos, labor). Had to pay 5k, warranty company wanted to replace using a used motor, but after arguing(infiniti service writer helped) new motor was determined. Dealer did hook me with all new engine components (wasnt included in original RO), didn't charge me the loaner I had for over a month, gave me extended warranty and other small goodies that made paying 5k worth it since the repairs did cost more than what the car was currently worth. I just got the car back on July 25th, brought it in June 7th. Once things were approved, took 1 week.

I want to update that the exact source of the coolant mixture was due to bad core (freeze) plugs on both cylinder heads. I didn't think about it at the time, but wish I had asked for pics before they sent the bad motor out.2016 Red sport
