is 5000 miles too long to wait for an oil change?

10K with synthetic for me,my way of helping out the environment in a small way.also helps on whats in my wallet.

By the way, when I was living in Europe I've never heard of or seen anyone do their oil change under 13,000 miles, synthetic or not. And last time I checked, their cars were running just fine :) And let's not forget, in Europe a 2 liter engine is a BIG engine!

I also don't really buy the theory that a smaller engine somehow makes more heat than a bigger engine. Yes, they do work harder, because you have to rev them up to get into their optimal power range. As far as I know, modern engines are much more efficient than 20-30 years ago, in fact they are so efficient that they don't produce enough heat to heat up the car in the winter and you need extra gadgets to warm up the car...

And even if it did make more heat, applying the same logic, wouldn't it be easier to cool as well? Because it's smaller it has less thermal mass, right?

Bigger engines last longer because they produce more power at a lower RPM and low RPM means longer life.

was told by head tech that TOYOTA will be going to 10,000 mile intervals and the use of 5w-20 . Not sure if synthetic or conventional or both .

I run AMSOIL synthetic, change the oil every 25K miles. Change the filter every 10K miles.

You are crazy man. Not only is that way too long, AMSOIL is not a very good synthetic to begin with.


My yaris is at 65,000km (40,389miles). I was using Castrol 5w30 conventional but switched to Mobil 1 5w30 Full Synthetic on my last oil change. I am choosing to go 8,000km (5000miles), using a Fram Tough Guard filter on my first oil change.

The first thing I noticed when I switched to Synthetic was my engine ran a little quieter. Second was just performance, it seemed to accelerate a bit quicker and smoother. I know the filter says it's good for 12,700km (7500miles) but I don't feel comfortable going that kind of distance. I do a lot of highway driving going back and forth to work so I will find out in a month how the oil works out.

Ok, amsoil states using their filters you CAN go that long, and it is excellent oil. Lets keep this as facts not speculation please. This is why oil threads go south

I think Amsoil issued a warning that their ea filter [made by WIX] in our Yaris needs to be changed every 5k miles, even though it's rated by Amsoil for about 25k miles....so yeah, I guess if you're instructed by Amsoil to change their 25k mile filter every 5k miles their oil will easily last the claimed 25k miles/1yr.

I find it interesting that Toyota will be switching to 10,000 mile oil change intervals . I'm willing to bet they will be using Amsoil or made by Amsoil .

If you do a comparison with Amsoil and Mobil1 like I did , you will come to the same conclusion that I did . At 5000 miles the Mobil1 was "black" while the Amsoil was still somewhat lucent . Visual inspection alone clearly (pun intended) shows that Amsoil is a superior product .

I change filter at 5K (Toyota) and my Amsoil at 10K .

i go about 8000-9000 on royal purple... no probs so far.

Oil changes are a different story between convention loil and synthetic IMO. I can see synth oil on a 10-15 or 20k oil change, but last I heard there is still a sludge issue in toyota engines,at least compared to say Honda(but they get the oil VERY hot as a way to keep from sludging) and my car has a lifetime drivetrain warranty as long as mfg maitainence is followed and records kept.I will use ONLY WIX or better yet Purolator PueONE So I will be doing my 3-5k oil changes for a long time! I noticed on the tranny dipstick (auto)it states no changes needed under normal use, 1st time I've seen that!

The dealer where I'm looking to buy offers this lifetime warranty. Do you have to take it to the dealer for every oil change? Can you take it to quickie lube & just save the receipt? Can you do the oil change yourself & save the oil/filter receipt?

Absolutely!
By (federal) law you do not have have your car serviced by the dealer to maintain the warranty.
Just save the receipts.

[n5odj]

Awesome. I'm pretty impressed by a lifetime warranty on a car. Reckon I'll run over there tomorrow & probably spend some money on this Toyota.

you think purolator is better than WIX?
