Come to think o fit, the lowest that I have seen the temperature read is -30C as well, even though it has been colder than that here in Saskatchewan this winter. The firecast is for -34C tomorrow and Sunday night. I'll take a peek at the dash to see if it states anything colder than -30C.
I'm impressed with how well the 4runner starts at those temps, even if I forget to plug in the block heater. The starter turns the engine over at close to the same speed when cold as compared to if the engine is already warm...impressive. I actually do not know what grade of oil is in my 4runner.....I just bought it a month ago from a toyota dealer, and it has whatever oil in it that they put in it (likely the 5W30 as recommended by the owners manual). IIRC, from some past research that I did into minumum pour temperatures of oils, Toyota oil scored well for cold weather performance.
