That is just a myth jdubau, MANY new vehicles come with synthetic oil in them from the factory, like BMW, many Chryslers, many Mercedes, just to name a few

No not a myth at all....those higher priced premium brands spend more time and money pre-conditioning their motor internals to mitigate early break-in synthetic oil usage.

OTHERWISE, for owners of other cars, one should NOT use synthetic oil before the engine is broken in, and to do so can effect engine performance down the road.

Chino quote "... Shut up!" Yes it is a myth, I will bust out some resources to back that up if you would like?

Good point.

My dealership "suggested" oil changes every 3,000 miles despite what the service manual says. Think about that.

this idea of every 3000 miles is still being thrown around as a marketing ploy for companies like jiffy lube. less frequent oil changes = less business for them, so they are still advertising 3000 mile oil changes for every car, regardless of what the manual says.

perfect examples, I do think the whole 3000 mile thing is to keep dependance on oil in general, it's like they are slingin crack

[Kaotic Lazagna]

my dealer recommends 5000 miles. bah, not really going to do that tho.

[Kaotic Lazagna]

okay, just filled up on gas (using syn. now). i got 40 mpg. that's up 2 with the conventional oil. plus, i was using the A/C and driving 70-75 mph.

Good Morning,

I joined this group just yesterday and this is my first post. I first changed my oil on my 07 S Sedan at 2,000 miles and have switched to Mobil 1 5-30 with OEM filters. I now have a filter/oil change every 5,000 miles. I commute daily and my combined mpg is 41 (my Yaris is now one year's old, 15,000 miles). Following is an interesting site I found that not only discusses oil, but other aspects of the car:

I found one thing on that site that already made me not trust it, it saaid Toyota has more sludge problems than any other, infacy it is Chrysler that has more sludge law suits,complates, problems, or what ever than anyone else

All makes have the gelling/sledge problem....it was Lexus that has been more publicized as of late, but if you do research you'll find the same issues with nearly ALL car makes. The bottom line is that regardless of the car make, if the car is allowed to collect condensation at night, it will have a sledge/gel problem with the oil....Lexus owners are more likely to have the $$ to make noise in court....one reason why you'll not hear of this issue from Hyundai owners ;-)

so was buying 5W-20 a bad thing? guy from NAPA said it was fine, and that 0W is only needed in extreme cold climates.

[Black Yaris]

5w20 is fine, don't mind Pavel, he lives in his own world.... If this easies your mind at all the Prius takes 5w-20 from the factory as well, many chryslers take 0w40 in ANY CLIMATE, that includes So. Cali

with regards to the oil grade, simply put, the lower the first number, the lower the outside temp can be for starting your car. it just means it can be freezing outside and your oil is still doing its job. the second number is the trickier one. i know that all small hondas (fits, civic, etc) can take in 20 viscosity oil, for better fuel efficiency (lower friction coeffecient in the engine). your oil will do just fine. it wont ruin your engine and you'll probably get better mpg because of the viscosity level. i havent seen any tsb regarding oil 5w or 0w-20 oil yet, but im sure if people here say it exists, then it DOES...

yup, getting better gas mileage with the 5W-20 synthetic oil.

I did some research on 5W-20 and 0W-20 and found that it will give better mileage, but may cause more engine wear over time compared with using 5W-30 or 0W-30. This was all discussed in a thread about the Toyota 5W-20 TSB. This is due to the size of the suspended particles staying the same but the film thickness is decreased. I'm sticking with 0W-30 and Napa Gold filters. Maybe even a mixture of the two weights. hmmm....
