Oil issues related to 1997 Toyota Tercel?
Hi friends,
My brother has a toyota tercel manual trans. it has almost 250000+ km on it.
The problem is that the engine oil gets too dark too fast. no matter which oil you put in it, after sometime in less miles, you check the oil and its black again.
also when he accelerates harder, a dark blue oil comes out of the exhaust. but in slow driving, the smoke is no where to be seen.
can anyone explain in detail what's going on here and what's broken and how much it will cost to get fixed? toyota is reliable so this problem seems strange. oil is always changed as mentioned in the manual.
Thanks.

Ok your's not a big problem. First; 250K is serious milleage. Don't know where you're from but if this is not big issue you should consider raising the oil rating to your tercel, say from 5w-30 to 10w-40 since it will provide a thicker film to the piston wall and cover the miro abrasions that are causing to much carbon to be absorbed by the oil via the piston rings at the cost of a little less MPG's. Also consider changing the valve seals; this is a simple (1 to 2 day) procedure but must be done by a good mechanic to reduce your blue smoke.
Toyotas are known to get oil dirty. At this milleage do not flush the engine but lower the oil change interval from 5000 to 3000 miles or even 2500 and after 2 or 3 changes you should see a difference.
Hope all this helps and that the tercel will give you many more years of enjoyment.
