What oil is best? and what ratio?

[Dub11]

I was a Toyota dealership tech for several years. We used the two jaw oil filter wrenches that connect to a 3/8" extension to remove them. Nobody ever used a tool to tighten an oil filter, there is absolutely no reason to do so.

We were telling people to change their oil at 3750 when I got out of it in late 2007. Does Toyota really say 10k nowadays? The only thing I take my vehicles to any kind of shop for is tires and alignments because a). I'm cheap, b). I don't have the machinery to do it, and c). I don't like having my car fixed according to someone else's schedule. Then, it's an independent place owned by two brothers.

Thats what they told me. Now I remember a while ago reading Toyota went from 7500 to 5000.And I work on my stuff and that also the main reason I like my older Honda's and Chevys but this van is under warranty so I want everything documented by there hand so that way if something takes a *s-word its on them.

Yup Toyota recommends 10k on Mobil one 0w-20 in all their vehicles now. Same cartridge filter across all models now too I believe.

Toyota mechanic I know says as long as you buy the filters from them and you write down the mileage showing your changes they can't say anything.

If I remember right the Sienna hold a little over 6 quarts and after pricing the stuff my self the oil change comes out to 10-15 more than me doing it my self.

Actually, as long as you change the oil and filter according to the manufacturer's specified mileage they have to warranty it, even if you use an aftermarket filter. Unless that has changed since 2007? When I was there I was amazed at the lengths service managers would go to get Toyota to warranty a neglected engine filled with sludge. The favorite tactic was drain what little oil was left and then redline it until it broke a rod. Short block time!

Switched the fuel back to red armor last week. The wife was trimming with project bent shaft and said that she could tell it was running better. I looked at her with a confused look and asked "so your saying oil makes a difference? " she huffed at me and went on destroying every weed in site. Lol she really likes that bent shaft running on red armor. Next week Dolmar synthetic lol gotta keep her on her toes. Lol

You married well!!

I have helped customers get questionable warranties also. Had a guy get a new crate 6.4 l powerjoke reciently. Dealer tried showing it was water in fuel he drained from the water seperator that was the cause of the crank spinning its main bearing s. Uh water seperaror aways have water in them shocker right.

I mixed some Woodland Pro synthetic up and ran a couple gallons, my 7900 was an absolute bear to restart after getting hot or refueling after running out with it, Back to red armor and it starts again fine.....Who knows.

Yeah my wife has a 2014 highlander and it's not near as cheap to change is as it is my Camry. Cost like $25 for me to do my Camry and $40ish to do hers. She said she would rather pay but I don't like the every 10k oil change and the over torqued tires but she won't listen. I guess when my cars still going fine at 300k and hers is long gone cause of sludge maybe she will listen the next time lol.

The synthetics don't produce sludge like dino oils. Oil doesn't wear out. Thw additives wear out and the oil gets dirty, but the base stock pretty much stays the same.

From what I've heard at least with the Toyota vehicles is the problem maybe isn't so much the oil but the oil filter is right on the edge at 10k heard of some people changing the oil and the filter just falling apart at a 10k oil change

Yeah I'm sure on my 4 cyl Camry it's fine but when they use the same filter from the 1.8 liter corolla to the 5.7 liter v8 tundra that's a lot of different variables for that filter to have to meet I bet it's pushing it to go 10k on a 5.7l v8 as far as filtering media goes.

I feel like motor oil does wear out. Heavy diesels start using oil after a certain amount of hours on the new oil change. Change it again and no consumption. Just my observation. But it does go that way

 

[RI Chevy]

I run 15K on my change intervals. No loss of oil.
I will mention that I do use a bypass oil filter as well as a regular filter. Removes the soot from the oil. Its like oil going through a dialysis treatment. I follow up with a UOA from Blackstone Labs. I get great results, and they always say I can go longer on the change interval, but I change it once a year.

Good point

 

[FergusonTO35]

Oil filters get filled with junk rather quickly, by design of course. I really don't see the point of trying to get 10k out of a filter. Even if you're using fancy pants 15k oil, the engine is still sending combustion by products into the oil which will be caught in the filter. For an extreme example, cut open a filter from an air cooled B&S or Kohler after about 20 hours. The oil will probably look pretty clean but the filter will look like it's filled with crude. By that time, the bypass will have opened and you are effectively running without a filter.

Even worse is "false oil". This is where an older engine is both burning oil and in turn replacing it with combustion by products and unburned fuel. It doesn't take much for this to happen and the engine may run great, have clean plugs, and not smoke. Unfortunately it means you are running with oil that is heavily diluted with wear causing agents. The only solution I know other than frequent rebuilds is to change your oil more often.

yeah oil wont sludge by itself a plugged pcv valve or worse coolant leaking into the oil will cause. if you runs non detergent oil in a combustion engine you bet your ass it will sludge.

the only other way for it sludge these days if the moron runs 20,000 miles on regular oil.

all diesel oil sold on the shelf at Walmart or oreilly auto is not really synthetic its just hydro cracked group III oil its plain dino oil that is made to perform like syn oil. even if it says full synthetic on the bottle.

 

[RI Chevy]

Not exactly true Jake. Walmart sells Mobil 1 5W40 Turbo Diesel oil. Full synthetic.
I think you may be referring to semi-synthetic oil.

The issue in this case is fuel dilution which isn't uncommon and some engines are worse than others , fuel gets into the oil and it loses it's viscosity .
IE: it was a 40 weight used on the last oil change but with the fuel dilution it has become like a 30 weight or less so with that they will start to use oil .
