I don't drive many miles per year or tow. In the past year and a few months I've totaled ~9000 and that was with a 2500 mile trip. The rest is city driving with mostly a 13 mile round trip to work. I'm in a very hot climate location. The truck is fairly new to me and I am currently using M1 0w40. The previous change used M1 5w30 HM and was pretty dark. I don't know which oil was used by the previous owner. I've heard this engine is easy on oil.
1. I change the oil/filter at 5k intervals. Considering such low annual miles, I was thinking of switching the filter every other time. The filter isn't that big and the sump takes about 6.5 quarts so I wouldn't think that the small amount left in the filter will affect the integrity of the new oil. It would mean putting the truck up on ramps and removing the skid plate only once a year, too.
2. The manual calls for 5w30, but considering the rave reviews and specs of M1 0w40 I thought I'd try it. The truck was a tad bit more sluggish before warming up, I thought, but I haven't noticed a drop in MPG. If I wasn't using this oil, I'd probably be using M1 5w30 HM, which I used for years in my last truck.
So, should I double the filter interval and should I still use the M1 0w40 or go back to the M1 5w30 HM? If not that 5w30 (maybe a 0w30???), which has the same accolades as 0w40?
Thank you.
Double filter interval and M1 0w40

I would stay with Mobil 1 HM 5W30. Its a great oil and that is what your vehicle specs.

Yeah 5w30 would be ideal, no reason to have a 0w40. Here in Phoenix it gets down to MAYBE 30 on a couple days so no 0w needed and your engine runs at the same temperature whether it's 60 outside or 117 outside, that's the beauty of a functional cooling system.
Get a filter rated for 10K or more miles, like a Mobil 1 filter.
I use them for (3) OCI; Remember the oil you are draining was properly lubing the engine minutes before you decided to drain it.
A lot of people let the oil drain for hours before buttoning it all back up; seems a bit silly since there are probably cups of it left in the engine anyway.

Great oil. Might be a bit thicker then you need but if you like it then keep using it.
As far as the filters go I'm doubling the interval on my vehicles. Filters get more efficient as the media loads,which means cleaner oil.
My vehicles go into astronomical mileages,running filters for 2 changes so obviously it's not hurting anything.
Similiar to what i am doing with the Clio.
Though i don't always leave the filter on for two intervals.
Tried Shell Ultra 5w40 this time for no reason other than finding it for a decent price.
Fuel economy is now just over 60mpg in mostly town running.
If you want to use 0w40 then go for it.
Many of the Clios miles have been completed with Mobil 1 0w40, sometimes New Life sometimes Turbo Diesel(not the same as TDT as in US)
Run oil and filter changes once a year and get a UOA after one year. I think a quality filter wix, fram ultra, m1, etc..and just change both once a year. I see no reason the m1 0w40 wouldnt hold up for 9k miles.
Mobil 1 0W40 is a great oil.
And you've got a great truck there...but why you're using an oil that doesn't meet specifications for your truck is beyond me...(please note: I am a 4 Runner fan...and my old truck specifies 10W40 in the summer...I generally run a 5W30...but I got this on sale for $1/QT...so, I am running it!)
I would just go back to a 5W30...and change the oil and filter each time...but there isn't a need to change it each year...other folks who put low miles on cars have shown good UOAs on oil that's been in the sump for 2 years...I would just change on miles...

With the kind of driving you do and your climate, the M1 0W-40 is a good choice. With a good filter you could change both at 10K mi. intervals and be in good shape.

If you get a Fram Ultra you can leave it on for 15,000 miles regardless of time in service, which means less time removing the skid plates. If you oversize, you can probably go 20k.
I'll try and cover some points here.
I chose to try the 0w40 since its a low 40, easy to obtain, and its reputation.
I'm using stock filters. Factory OCIs are 7500 miles so I don't think they'll suddenly deteriorate over the last 2500 if I do the 5k/oil then 10k/filter and oil changes.

Thank you.
First, a good filter intended for longer intervals is important.
Second, don't listen to a bunch of advice, much of which may be misguided. Just run the two oils of interest and compare their performance directly, oil analysis included.
Manufacturer recommendations, especially on older vehicles, can be pretty basic and vague. My 4AGE has factory recommendations from 30 to 50 weights. It leaves a lot of room for consideration of service conditions. The conditions the engine was "designed" for is often a matter of assumption and interpretation. So only your specific performance comparison, for your conditions, really matter in the end.
