Engine Oil - What to use ???

Hi All,
Time to change the engine oil.
The owner used regular 10W30 @ 5000 Km
At 185 000 Km, should I use synthetic, High mileage or just regular oil ?
In my 2006 Tacoma, I was changing oil @ 8000 Km....can I do the same with my 1999 RAV or should I do it @ 5000 Km ?

The book says every 5,000 miles, but my rav has 103,000 miles so I change mine every 3,000 miles and i just started using synthetic oil. I use mobile1 5w-30. I think they recommend the 5w30 over the 10w30 because it is good for all types of weather.

sl4nucrewprod4, is correct. 5W30 is recommended by Toyota. Just look at your OEM oil cap, it says it there. My RAV4 is a 97. I still use 5W-30, regardless of its 80,000+ miles. But I also use Lucas Oil Stabilizer. It quite the engine noise quite a bit.

Took my new to me 2000 112,000 Mi. RAV to the Toyota dealer for a "Synthetic" oil change. They used Mobil 1 5W-30. Now I know what use in the future when I do it my self. HTH, YMMV.


Edit ADD: 5K Mi. change recommended on the sticker they applied.

2 nd owner. 112,000 Mi on the clock.
Update, 5 Yrs, 50 k mi later, still rolling.

I doubt it makes any difference at all.
People love their brand oil.

If you want to go longer between changes, run synthetic, although it will cost you more to do so.

Whydo I say the brand/type of oil makes no difference?
Experiance.
My son had a camry (4 cylinder) that was owned by a series of students who did not bother to change the oil or check the level of it, or change the coolant, tended to get drunk and run off the road, etc.
When we got rid of it, it had 250,000 MILES on it, it did not smoke, burn oil or leak, and the next student is still driving it (and crashing).

I am sure when it did get oil changes, they were NOT synthetic...

No matter what oil you use, you are not going to wear out an engine.

The rest of the rav will likely fail way before the engine.

Hi, I am moving to frosted Calgary from warm and sunny Denver... I just got an engine block heater installed and swithed to synthetic oil... Toyota service advisor told me that I can not go back to regular oil once I used synthetic oil... Is there any truth to that? Anyone?

I think that he is full of it. Synthetic oil is superior to coventional oil in all aspects except price. In fact, when you rebuild an engine they recommend breaking it in with conventional oil. The synthetic oil is too slippery and the rings don't seat in properly on the cylinder wall. The synthetic would be better for the camshaft wear but you need to get the rings to seat so intial run is done with conventional oil till the first oil change. In very cold weather you will be glad you are running synthetic. The viscosity of conventional oil tends to make it like molasses when the temperature plummets. Have fun in Calgary.

While you want to run thinner oil in really cold places, or cold places with lots of short trips, from what I understand, 5w30 is 5w30, it makes no difference if the base stock is synthetic or dino oil.

Also, from what I have heard, synthetic pays off in two places, extended changes where you get the oil analyzed and replace it when its worn out, and at extreme temps, (turbo motors or racing).
