Mixing Engine Oil

[Bonjaz]

My 3 xr6t's have all enjoyed nulon 10-40, even my misses swift likes it

[SuckSqueezeBangBlow]

Edge 0w40 or Edge10w60

[Never had any say Panda]

Wouldn't 10w-60 be a bit much for the fords?

5 is not too light. 5 is in fact thicker than 40, as this is when the oil is cold, and its viscosity changes as it goes to 40 which is at operating temp.

So a 5w40 is fine a 0w40 is fine. All it means is that the starting viscosity of the oil is closer to what the engine requires at operating temp.

You don't say!

Makes me wonder why N/A engines use 10-40 and the T uses 15-40... Meh, never mind I'm sure you know best.

Mine loves 10w60. Very important to let the car warm up properly though. I drive 20 Ks before I give it a good thrashing.

[sexual harrassment panda]

what he said

let it warm up properly and 10w60 is best

[Adam]

Are you guys going off the temp gauge or an aftermarket oil temp gauge?

I've found that the coolant gets up to temp much quicker than the oil.

[Paulie2256]

Nah just going by 30 mins of driving or 20ks distance. Don't go off the coolant temp.

[SuckSqueezeBangBlow]

Oil temp gauge for me. FWIW Nulon 10w40 and Edge 0w40 would go up to and past 120c when thrashing hard for awhile, but Edge 10w60 never went past 115c. If I put an oil cooler on ill go back to Edge 0w40

[xrBlitz]

So Edge 10w60 with a 30min warm up before giving it a squirt, or Edge 0w40 with oil cooler if your thrashing it for a long duration, what if you only boost off the line at a set of lights once in a blue moon, would Edge 0w40 be fine to use? And for everyday driving?

Also, I ended up buying Transmax Z for the t56, I had to buy 2x4Lts bottle at $75 each as they didn't have any 1Lt or 2Lt bottle at any of the local ripco or superheap, so my question is, what sort of shelf life does an open bottle of this stuff last for, I do around 10k km a year in the car so I probably won't need to change it for 2 or so years.
