Old good xr3i oil question (mk4)
 

Well my escorts oil change is comming right up.

P.t I drive on a good 10w/40 oil, but i start ticking a little in the first min (not alot you need to concentrate to hear it) but as its going to get way colder here in denmark i want to spare my engine for to much cold wear.

I mostly use my car from my house to work - approx 6 kilometers each way, and some cold days the engine oil dont even get 60 degrees hot.

Some people tells me that 15w40 oil would remove the ticking, but as it being thicker at low temperatures than my current oil i think its a mistake.

Im thinking of using a 5w40 castroll oil at the next 6500 kilometeres, would it go for my escort xr3i?

1.6 8v 102 hp

So i guess its 5w40 vs 15w40.

Ps. SOme people says you can use 10/50 in the summer? As it ticks a little still when hot.


OBS: My cam and lifter + valves was changed 4000 miles ago.

The ticking is down to tired tappets losing pressure.
Don't put a thicker oil in it, but do try and give it a good thrash once a week, and with the short trips always, change the oil more often, it's not getting hot enough(the oil) to burn off the oxidants(pollution) in it either.

Hmm the lifters almost new, but im gonna try with the 5w40 oil, and oil clean. I do use the car for cruising as well some days/night and im flooring it there,

Thank you for your answer.


If anybody else got a reply your welcome :)

BUT!"!! Can you drive at winter with a 10w/40 engine oil with out "damageing" it ?

What would be best? A castol 10w40 or a 5w40?

Either oil can be used in winter or summer without risk of damage.
The first number is the viscosity(thickness) of the oil at a lower temp, the lower the number the thinner it is, the 2nd number is the thickness at a higher temp.
Note that although it would appear from the number to get thicker as it gets hotter, it doesn't, just the odd ways the temps are measured different.
If you have a choice use 5W40, it will circulate a fraction better when cold, but 10W40 certainly won't kill it.
