I run 0w20 Nov-April and 5w30 May-Oct. As stated, each of those intervals gets approx 8-9k miles on M1 EP.

true..the problem is that the audience does not have the vocabulary and understanding of the technical aspects to know that 0w40 is just not that much thicker than 0w20. They are all in the range of “engine oil” which is a narrow range in itself.

It’s not actually that bad to change the filter, but it is more aggravation than it should be. I wish they would have given us an access hole in the skid plate.

I have an '18 4runner. Using 5W-30 in it since the first oil change, which I did myself. 5K intervals. The Maint. light reminds me. I may stretch out to 7500.
On another subject, don't forget your drive shaft grease points, there are 5 or 6. I had read on the 4runner forums that some dealers were not greasing these as part of the 2yr maint. program, so it may be a good idea to verify that with your dealer.
And yes removal of the front skid plate for access to the filter is a little bit of a PITA, and I could see people stripping out the threads.

UOAs to prove it works lol

40wt oil is speced for this engine all over the world and the full saps Mobil (and Castrol) products are on the brink of being 30s anyways. Hugely strong add packs and TBN and they both meet the strictest oil specs on the planet.

Want clean pistons, low cam and bearing wear? See my sig


Ok. Good to know! Has using 0w40 impact your MPG at all? I know these vehicles aren't exactly known for it, but I'm just curious. Since you're a stout Toyota driver, any reason why you use 0w40 instead of 0w20 or 5w30?

I'll be honest, I don't have a very deep understanding of the oils and weight, that's why I'm here smile. All I know is what the factory fill weights are for my cars, and I just stick to it. I know they recommend and allow other weights, but I've kinda fallen into the "routine and commonality" system that I don't stray from because I don't know much about it and combine what I read in forums, what the manual says, and what they use for maintenance at a dealership. Like for my Audi, it's 5w40 Motul, else it's 0w40 from Castrol. I know I can use 5w30, but for some reason I'm afraid(?) to use it when it is also recommended; yet the VAG community loves that oil weight as a unicorn for some reason.

Simple fact is the vehicle will last 200k+ with the recommended oil, and there's no real evidence that using thicker oils offer any advantages in normal, every day driving.

I haven't looked at your manual, but don't trust the dealer to know the proper OCI.

I had a 2011 Tacoma with the 2TR-FE that came with synthetic 0w20 from the factory. The manual recommended 5k OCI even with synthetic oils. The dealer tried to argue with me and I had to bring my manual and several other resources for them to honor the 5k OCI under the 25k complimentary service plan.

They also both under- and over-filled it. I only took it in three times before I decided it wasn't worth it.

Check your manual, hold them to account.

I'm pretty much leaning towards not even using them for the oil change. It's hard to trust dealerships for maintenance unless it's a big job. Don't need someone half assing it.

For what it worth...

I am running 0w-30 Amsoil Sig. Series in my 2018 4Runner TRD Off-Road. The engine is quieter than factory fill. Maybe due to it is breaking in. I am also running the TRD oil filter.

I forwent the fee oil changes. I have done my own work for 30+ years and not about to let any one touch my baby.

2nd close choice would have been Pennzoil Platinum 5w-30 if I didn't already have an Amsoil account.

My OCI will be... not sure yet. Factory fill came out at 1400 miles. Probably every 2 years since my miles per year are really low.

I did see some metal filings in the oil filter housing. Hopefully normal from break-in. The vehicle will probably outlast me.

I do agree you can run almost anything between 0w-20 and 15w-40 for the appropriate climate and drain interval and easily get 250,000 miles out of it.

Just my .02

How long do you plan on keeping your 2020 4Runner?

It's hard for me to separate the any type of possible EPA intervention as well as your warranty period, when it comes to 10K OCI's.

Could the vehicle live a happy life past 200K miles with the factory recommended OCI's? Perhaps...hard to say.

Driving around with an oil temp/pressure gauge now I see that it takes quite awhile for the oil temp to get above 180 deg F..the oil temp tends to mimic the coolant temp but takes much longer to get there.

Only way I would stretch any OCI past 5K would be with a lab report every 1500 miles past 5K...but personally I would be changing the oil at 5K.

Our 2014 Highlander goes in every 5-6K for the OCI on 0W-20....I'm fine with the added frequency.

If xW20 makes you nervous use a xW30 - nothing bad will happen

I couldn't do it. 5K maximum for most owners. Probably 3K (6 months) with those 8 mile trips. I'm personally back to 3K but I am a long term keeper.
