You know me too well.Are you an old SVTPERFORMANCE guy. These young kids have no idea how bad we could roast them. BBQ tick. Ticking. Typewriter noise. Rattle. Piston slap. Lots of keyboard mechanics around here

except if you write your manual for the entire US, which most do with the possible exception of California, you have to go with what the extremes area, both hot and cold. They are not going to publish a Minnesota manual, a Florida manual etc. especially as there could be people who would want it tested to see if it changed the overall mileage. Therefore, they have to recommend a general oil that will work most places.I used to live in Chicago. I've been to Minneapolis during the winter more times than I care to count. My vehicles are stored outside, uncovered. I've ridden my motorcycles in howling 9F temps. Mustangs are rarely the only car a person owns and rarely cranked up at extreme cold temp. Yes single digits can happen as far south as NC and low teens even as far as Alabama. When it's extreme cold out (below 20F, let alone 0F) the number of people who take the Mustang to work at o-dark-thirty is downright tiny compared to the total population of owners. And the people that do very likely have an indoor garage or engine-block heaters. I did not suggest running 5w was a bad thing, just that given the distribution of ambient temps, way overkill for a very large cross-section of owners.
Which brand are you using?My 2016 seems to really like 5W30 or 5W40. I haven't put 5W20 in the thing for ages.
Yep ... apparently only a confused dealership.Ford is not recommending 5w-50 .. there are no bulletins that state anything of the sort.
Hi,My dealer provided the first three oil changes free. I asked them to please use 5w30 instead of 5w20 and offered to pay any difference. As far as I know they did what I requested, at no extra cost and shown on the reciept was the 5w 30. My engine has ran without any tick at all. I did my own oil change this past weekend and used my standard 5w30 mobil 1.
If you think this place is bad about oil discussions, go over to bobistheoilguy and see what goes on there.You guys have way to much time invested into this oil discussion. I mean seriously...It's informative, but damn. I mean, damn...
I got the same thing. It goes away once you drive around. It’s the lift off rattle. Not the same as the 2k rattle. There was a tsb for the f150 to replace the heat shield between the transmission and motor, or something of that sort. I don’t know if it fixes it, but there is no tsb for the mustangs. Every time I take it to the dealer it stops making that noise.Hi,
Do you have the 2k rattle when letting off the throttle paddle?
Like mine:
Thanks
Mine will keep doing it 24/7, the dealer heard it in both last two visits and they keep saying its normal.I got the same thing. It goes away once you drive around. It’s the lift off rattle.

You won't lose any oil flow volume to parts that are force fed by the positive displacement oil pump. You could lose some oil flow if the engine is revved high before the oil gets to full operating temperature - that's a bad thing to do regardless of what viscosity of oil is used. If the PD oil pump goes into pressure relief (due to cold thick oil), then you would lose some oil flow volume to the oiling system. But even 10W-40 or 5W-50 when fully hot should not put the pump in pressure relief, so you're not going to lose oil flow volume in that case. Keep high revs down until the oil is at full operating temperature.So will it hurt to put 5W50 in YOUR car? Probably not, but bear in mind that all else being equal, heavier weight oil will yield higher oil pressure, but lower overall flow. Oil has 3 jobs - to act as an oil film bearing surface, to provide cooling, and to provide lubrication - in that order of importance. Your 50 weight might improve oil film strength, but at the detriment of cooling and lubrication which depend on flow. Unless your operating temps are up high enough to warrant it, skip the race weight oil and stay closer to what the manufacturer recommends.
