I just monitored different sensors for the first time with my MHD flasher. I've never seen an engine reach normal operating temperature so quickly. As soon as the temp gauge in the dash reaches four bars, which takes about two miles, both coolant and oil are 200 degrees.

Coolant is the important one. Hot coolant means the block and everything is nice and hot and finished expanding etc.
Oil works at any temperature so you don't have to wait till it's fully heated up before you start driving sporty.

I'm not so sure about that. In all the previous cars I've owned coolant came up to 200 much sooner than oil. In my son's 2017 Mustang GT the oil temp gauge was not numerical. It had cold, normal, and hot zones. The coolant temp reached 200 several minutes before the oil temp was considered normal. In the 2016 GT350 I traded in on my Supra oil pressure still read 100 psi when the coolant and head reach 200 degrees. It took another mile or so for the pressure to come down.

That's normal. Oil takes longer to get up to temp than coolant does. Oil is thicker than liquid. Well maybe not that 0W20 pisswater the Supra here in the U.S. gets put in. I'd imagine a heavier weight takes a little longer to heat up too.

That's what I was thinking. Both vehicles I mentioned use 5W-50. The Supra/BMW 0W-20 makes me nervous.

The rest of the world gets 5w30 in the B58. I'm swapping it out as soon as I get mine. It's EPA Bullshit to improve cafe ratings.

That and the 10,000 mile first "free" oil change. I'm debating. I'm leasing my car so engine wear/longevity is not a major concern. Even if I buy it at the end of the three years I'll have plenty of warranty left.

what are you smoking? In Hondas, in order for vtec to engage, the coolant and oil temperature has to be up to par for it to be working.....

You got nothing to be nervous about. The first number actually helps you with the turbo engine lubrication upon cold startup. Most people donā€™t realize that. If your really worried about it, run some 0w30 or 0w40 oil. The GTR r35 runs 0w40z

Does the B58 have Vtec? No? K then.

What is "turbo engine lubrication"? You shouldn't even be achieving RPM's close to activating the turbo until the oil is at full temp.

The first number simply indicates the weight of the oil at startup. Thin 0 weight at start and then 20 weight when at full temp.

He has every right to be nervous and Danny is spot on when he says we are only spec'd 0W20 in the states because of bullshit CAFE in order to meet EPA numbers. No chance in hell I would run a water thin 20 weight in any performance motor just to achieve an extra 2-3 mpg. Literally almost every application of 0W20 being spec'd here will show the manufacturer spec'ing a higher weight in the EU, Japan and abroad. The Golf R I sold recently was the same. Hell even the S2000 I had 20 years ago was the same.

A 0 cold weight is really only beneficial in colder climates. I'd much rather run a 5W30 or 5W40 in hotter climates, like here in Houston, for the added film strength especially when you consider how hard a turbo motor is on oil typically shearing it down a weight throughout the OCI. You run a 0W20 and it will be a 10 weight in no time.

When I get my 2021 I'll be dumping the 0W20 at my buddy's shop within an hour of picking it up and filling it with Redline 5W30.

I agree. I live in central California where it practically never freezes but routinely hits 100+ in the summer. I'm going to change mine when I hit 1000 miles.

I just watched a video on changing the oil. Boyota makes it super simple with the little removable cover so I'm going to do it myself this weekend. I'm not going to worry about changing the filter.
