gonna need some oil.
gonna change all fluids actually but one is just confusing me... engine oil.
till now, PO used some castrol magnatec 5w40.
imho, not dense enough for an engine so used.
on top of that, 1kg of castrol magnatec is about....mumble...fast eur-dollar conversions....damn math.......damn brain....: about 20$.
now, for a bit more, for like.... 30$ i can get 5kg of some Wurth 10w50. i really doubt there is more than just the slightest quality difference. not even worth mentioning.
am i right?
should i stick to some more expensive fluids? is an engine as old and used as mine really worth it? could it feel any difference if i spend my money on a way more expensive oil?
Is it a synthetic oil that has been used in the past? If it is I would continue to use synthetic. It lasts longer and is more heat resistant than dino. It also has less ash content. You can go longer between oil changes with a good synthetic as well.
I use what ever high mileage blend is on sale and change the oil more frequently until I fix my oil pan leak. Then I will switch to synthetic.
I had 10w 30 in it but during winter it gets to thick and I hear a knock at start up. I switched to 0w 40 and that helped a lot. It's super thin at start up and circulates better but is thicker at operating temperature.
