5W-20 vs 5W-30 Motor Oil - Toyota Yaris Forums

5-20 oil and 0-20 oil is widely believed to improve fuel economy and in upsstate NY in winter it will ceertainly improve starting.

Almost certainly in older cars it will however lead to increased oil consumption. My wifes 05 Camry with 120k on it used to go a full 5000 miles with minimal oil consumption. Now its uses a quart in ~2000 miles. This after 5000 miles the oil level will become dangerously low if none is added. (which Im sure most people dont do)

So now I use 10-30 in that car and Im going ~4000 miles to a quart.

I would request 5-30 oil from the people who change your oil. Might be a problem in summer with 5-20 in there. But probably no harm to leave it as is until July.
