I have a stash of Mobil1 0W-40 oil I purchased for a european car which I sold. I also have a 2009 Tocoma 2.7 liter 4banger. I normally use 5W-30 on the tacoma.
But, since I have this stash of Mobil1 0W-40 synthetic, could I use it on the Tacoma? Will it cause any long term damage if I don't use the recommended 5W-30? I live in southern Texas if that matters.
