5w20?
I am wondering if 5W20 could be used in cars that use 5W30 as standard oil. I live in Vancouver BC, so the temperature is not hot. The hottest day in the year is only 79 degress F. Do you think I can use it?
PS. I want answer quick, but people on the other forums are sleeping or something.

Use what is recommended by the manufacturer
Your engine was engineered with a specific oil type to meet specific tolerances. I would stick with the specs.
Is it worth ruining your engine? What will you gain, 2 mph? How long will that take to pay for a new engine, if anything occurred?

Not a Blowhole
Even 79 degrees that would be pushing it a bit.
However, if you use 5W20 G5 lube, then the added headroom of the oil can easily work in your situation. G5's are ester-based synoils such as RedLne and some Motul.
I am going the other way - using a 5w30 G5 lube in my TL-S for reserve film strength in the bearings, rings, and cam lobes.
The G5 has better cold weather performance than even the sewing machine oil 20 weight.
