the parts department at the dealership has a little laminated placemat thing on the countertop who illustrates in a bar-graph fashion which oil weight for which car, based on year. *iirc*, no car *changed* its reccomended oil weight for the duration of a bar. i think it went to the '05 model year.kapps said:I was just up at my Honda dealer last weekend and I saw they had a quart of 5w-20 oil out in a display cabinet.
What you have to realize is the oil changes temperature almost immediately and depending on how your oil temp gauge is marked, you might not see an indication of the change for 15 minutes. The oil will change in temperarture before the coolant will.Dougie said:I have an oil temperature gauge in my Miata, and it takes about 15 minutes for the oil to get warm.
And at what tempurature do you think oil weight changes? Lower than 140 degrees. So my point is it doesn't matter what your gauge shows because the oil changes weight well before you see the gauge needle move.Dougie said:The lowest marking on the gauge is 140 degrees F, and it normally runs at about 160--after a loooong warmup. The highest it's ever been is around 220.
Only Mobil 1 stopped making 0W-20 synthetic oil, not other oil manufactures.meow77 said:I think 0w 20 not being available is a farse... I see it in most shops and whenever I ask the shops if they have stopped making it I get a blank look...
