0w20 Oil Life

I've always put conventional 5w30 oil in my truck every 5k miles.

The last time I went to the dealership, they put 0w20 synthetic oil in my truck and said it was good for 10k miles.

My truck has a little under 70k miles on it, is 10k miles between changes of 0w20 accurate or should I keep changing it every 5k?

 

Drain that oil and put the 5W-30 back in,change Dealerships !

 

What is the Toyota recommended viscosity oil for your truck? That is what they should have put in it. 0W20 is what some of the newer engine designs use [My 2015 FJC did] but not what the gen 2 Taco's use. They probably had a bunch of bulk 0W20 on hand and went ''Ehhhhhhhh, good enough.''

 

My 2.7 is supposed to run 0w-20. It's on the fill cap. Every 5k miles, I drain out the old and refill with new. Along with an OEM filter. Myself.
0w-20 is ONLY a synthetic oil, to my knowledge.

I will never run conventional in it.

Like the other guy said, change dealers or change it yourself. Much safer.

 

If it's a 2.7L with the larger (V6) oil filter you are totally good to run 0w20 for 10K.

 

Take a gander at this motor oil 101.
10k seems a little long but some guys on here do it, but only with a synthetic and you need to check your oil every 3k miles or 3 months which ever comes first and top off if low. Also change the stock filter out at 5k miles and top off the oil.
You could also send a oil sample off to Blackstone laboratories.

 

Thanks for the input. I usually change the oil myself, but I went ahead and had the dealership do it since I was already there having another service done. Shouldn't have assumed they would use the correct oil. I learned my lesson.

I'll make sure to do it myself next time and use 5w30.

 

That's pretty much shit for the dealer to do that, probably charged you too much also.

Got a copy of your repair order?

 

Change your oil to 5w-30 as the engineers designed it.
Change it again in 5K miles.
Don’t believe the 10K mile crap unless you are a Nazi environmentalist.
Change dealers.

 

Any synthetic oil will last 10K +. The thinner 0-20 oil may give you better gas mileage but may also leak from valve covers, and burn more during oil changes.

 

I am no engineer, but the oil manufacturers have been saying change your oil every 3K for as long as I can remember. Then they say their oil last longer now than ever before. I would go with what the vehicle manufacturer recommends. Also pay attention to the oil on dipstick regularly. You can see the discoloration of old, used, burnt oil. I can't explain why, but I prefer synthetic oil. I took a hydraulics class once at work and the number one reason for failures of machinery in hydraulics was contamination. Good quality filters and paying attention to the oil is a must. On toyota's use only Toyota filters, their inexpensive.

 

Synthetic is ok to go every 10k miles.

Conventional needs to be changed every 5k.

 

I sent my oil to Blackstone labs for an analysis and based on that sample they said go to 10k. I'll follow their advise.

 

My dealer did this after engine service last week. It must be a thing. Sounds like I'll be draining and replacing with 5w-30 again.

 

Shortly before I purchased my 2014 new I came across a memo sent out by ToyMoCo to all its dealers service departments instructing them to back-spec the oil viscosity to the lighter weight oil on most of the engines. The exception was the 1GR-FE in the Tacoma. For it they were still to use 5w-30. I found the memo strange because IIRC other iterations of the 4.0 engine in other models were on the list to be back-spec but not the Tacoma. I believe the memo likely appeared sometime in the later half of 2013 or early 2014.

 

My wife's 16 tundra runs 0w-20 and the oil change interval is 10k, but I would run 5w-30 in your taco. If you leave it in I would check the level more often just to be safe.

 

This document is not the memo I saw because you will see at the bottom of the attachment link that it is dated April 2, 2014, but I had already reviewed the corporate memo from a very short time earlier than this date. Nonetheless, look at what it says for the V6 in the Tacoma. Conventional 5w-30 you say?

That is odd. That said I've been running full synthetic 5w30 in my 07 4.0l 4runner for the last 30000 miles.

 

also @Torspd

Yeah, its real odd. I'm also tagging Torspd to see get his take on why Toy's insistence of only a conventional type oil for the 1GR-FE.

 

Even the new engines that spec 0W20 for US cafe standards spec 5W30 in Europe.

Also, a 0W20 can be a heavy 20 weight and actually be 0W29 (i.e. Red Line) almost a 30wt. But, I digress.

You’ll be fine with a synth 0W20. Most 5W30 oils even synthetic like Mobil 1 shear down to a 20wt anyhow.
