Oil Changes

[mandiees]

How often should I be getting the oil changed? Anyone used synthetic for their Yaris?

[jambo101]

For warantee purposes i would stick with dealer/owners manual recommended intervals which would be 5000 miles or 8000 kilometers. I switched to Mobil1 on the first oil change.

I did the same : switched to synthetic at the first change. Great on -30*celcius cold starts, keeps up with heat on warm summer days.

As soon as hit 100 000km, I started doing changes every 10 000km.

You should do them at least every 8000 Kms
I've been doing them every 5000 Kms

As soon as hit 100 000km, I started doing changes every 10 000km.

Yes I know that on the bottle it says that it's good for 10,000 Kms but you should keep in mind that you live in Montreal and you should follow the servcie recomendations for harsh weather climates. The only thing you're doing by extending the interval between oil changes is asking for a problem.

depending on the mileage you do (lot of highway miles or sewvere service (stop and go, lots of ilding) you can use a quality dino. Syn is really not needed unless doing extended drains or doinf=g lots of cold starts in sub freezing temperatures or 130F weather.

dino oil handles cold and heat just as good, who is operating there car in 150 degree weather?

I Change My Oil And Filter On My 08 Yaris Sedan S Every 3000 Mi, With Toyota Oil And Toyota Filter. This Is Cheap Insurance And Keeps Engine Clean Inside. I Have 10000 Mi And Overall Avg Mpg Is 43.5.

i average 40mpg with my corolla.

changing at anything under 5K is a waste. but to each their own

5K/6month is the new 3K/3month routine

I use super tech synthetic from wally world.
Runs $15 for 5 qts.
I've been running this oil in my motorcycle which has solid lifters,and the bike runs extremely quiet.
Solid lifter engine's are notorious for loud valve trains.

Synthetic oil is formed from a pure gas,which has absolutely no microscopic contaminants like conventional oil,which can change to sludge in your motor,due to heat.
I'm quite sure synthetic oil lubricates much better than conventional oil.

Wow, syn oil is formed from a gas???? Who would have thought!

[tankowoe]

I change the oil whenever my Wal-Mart sticker says I should...

Ha, no, actually I do it every 5k miles, per many others. I do use synthetic but couldn't really say if it makes a difference or not.

I agree that anything under 5000 Km is likely a waist of good oil although short trips in the winter without sufficient warm up may dictate a more frequent change interval. I've gone 10,000 Km before on our 01 Corolla but didn't do that as a rule. Longer drain intervals shouldn't be an issue though if you are spending extra money on a good quality synthetic.

Sticking to the manufacturer's 8000 Km would be a good idea overall though if you are concerned about warranty and is more than within the capability of any of the better petroleum oils out there. I prefer European lubricants and use Motul or Elf/Total fuel conserving 5/30 in my 06 4Runner V8 and am consistently getting 26 mpg overall in the summer on the Motul Eco-Nergy 5/30. I haven't put synthetic in the Yaris yet as we are only at 1200 Km. Am impressed though to date as the first tank yielded 53 mpg mostly highway and the second 48 overall on the factory oil.

25K OR 1 year, whichever comes first. 17K for severe service! Dont just assume you can automatically go 25K and all be well. Still have to check dipstick every so often and add make up oil if needed

I noticed while shopping for oil filters the book notes to change oil every 3,000 miles on my yaris,although it lists it as a canadian model only.
I think they have sludge problems with the tiny 1.5 motors.
I don't like to waste resources,but cars aren't cheap.
Changing the oil every 3 months or 3,000 miles is cheap insurance against having to retire my car early.
I'd guess using the cheapest oil that meats specs and changing every 3,000 would be smarter than using expensive oil and changing once per year,IMHO.

Mobile-1 every 3k miles!! The only way to go!!
