Yep my Mazda's warranty is up and I'm moving on to 5W-30 for winters and 0W-40 summer. Using up the stash now that I'm 81.
5W-30 for everything?

A higher winter rating for winter and a lower winter rating for summer?
It doesn't get cold enough in WA to make a difference. Most people in the continental US can ignore the "W" part of oil viscosity.

I live in Washington. We see single digits at times and some healthy northeastern winds in the winter and have never worried about the oil in our cars. However my 96 7.3 Powerstoke, now she is a different animal and is not happy at all without being plugged in and/or a 5 winter rating oil in the winter!
I'll speak for myself. When I walk thru the garage and see 6 jugs of Mobil1 ESP 0W-30 oil on the shelf I know I have 6 jugs for all cars. Not 2 jugs for the Diesel, none for the Ford, and 4 for the Malibu & Trax. Nothing more aggravating than to pull the drain plug on a car and then find that you don't have any oil for it.
Simplifying stock on hand calms OCD, saves money and can divert disaster on a Sunday night after stores have closed.

IF you feel Mobil ESP 0-30 is a great choice without compromising for all of your vehicles then that's winning and the way to go.
I haven't drained the oil from a vehicle without first verifying I have enough oil, a filter, and enough empty containers for the used oil to go into.
why esp over fs 0w40?

I never have that issue because as soon as I use up a jug of oil I grab another one the next time it’s on sale and sometimes I’ll grab another as well. I’ll never be caught without the right oil on hand and with a lot of people here having a big stash I think most are going to have what they need on hand at all times.

I have been suffering OilChangeDelution or Dementia?
for many years. What does it mean? Symptoms? Well mine simply mean that I always have enough oil and filters on hand for about a years worth for each vehicle we own. Just something I started doing years ago.

I buy the 20qt boxes and 5W30 just fits better for everything. The two J-Series Honda's don't care, the F150 is still in warranty and it meets that spec, and the kids Jeep will drink 0W20 like a sailor, so 5W30 it is for all of them. (R&P For all)
Just like the 20qt box of Maxlife I bought. It is going in the F150's transfer case in about 2000 miles here when I do the 10,000 mile service on the diffs/trans/transfer case.
It’s at least twice as manageable.
A year’s worth? That not even close to pathological. You need to have an amount that is in excess of what the car’s remaining expected lifetime is.I have been suffering OilChangeDelution or Dementia?
That's actually not a bad point.
If they kid decided to get rid of her (fake) Jeep, then I would have 0W20 (If we were using the OE Spec) on hand with nothing to use it in. I mean, I could use it in the Honda cars as they both spec 5W20, but they'd probably start leaking out of everywhere at this point as old as they are. Certainly can't use it in the PowerBoost. So keeping a 'universal' oil on hand has that positive as well.

Well with these old weary bones (bad neck, shoulder, hip, knees, back, ankles etc.. think Tin Man Wizard of Oz) I have slowed way down so much the past several years. I do not even put near 5000mi a year on my car anymore. Still change it at least once every 12 mo
anyway.It's just as available and at a similar price point as the Full SAPS stuff and arguably a better more modern formulation, and in terms of viscosity, I pretty much view all the off the shelf Xw30 and Xw40 C3 and A3/B4 oils to be all about the same the 40s are usually just over the edge of 30 and the 30s are right on the edge of being 40 and they all have to have a HTHS viscosity above 3.5 .
Can I run 5W30 in my 13' CRV with the K-24 ? Has 615k on just 0W20 it's whole life....Trying to go thru my stash of 5qt jugs, and see which I have more of. The stash will last years. There all full synthetic name brand oils. Eventually want to run VRP 5w30 across the board for the 03' / 06/ 13/ Toyota's and the 1 Honda . All 4 bangers. Temps from 15-95 degrees,,a few colder snaps here and there in NY. It will make my shelf much easier to just grab the same jug, and not go searching for different weights. Any help would be appreciated

The K24 isn't going to care.
I switched to 5w30 in everything Daughters Hyundai Santa Fe wife's Toyota 4Runner and My Tundra they call for 0w20 and 5w20.
I lived on 5w30 for years and went tons of miles we never heard of engine failures years ago like we do now.
