Engine oil FUCHS or Motorcraft

4.5 L is the Ideal for Mazda 6 2.5 non turbo, I'm from the same country as you. I'm using fuchs titan 5w30 for two years and I recommend you do the same, I noticed quieter engine.

Só compro óleo original na concessionária e da Motorcraft conforme manual.

switch to 5w20 as according to fords bulletin for oil, i been using motorcraft synthetic blend for 26 yrs

Fuchs Titan GT1 5w30.

'17 f150 5.0l with 150k running 5w-20 motorcraft. Not a single problem and this was used to haul a 12' steel enclosed trailer loaded from day 1 and the wind blows a LOT here. Doesnt use a drop of oil.

Fuchs is excellent oil, run it in my nismo 370z cause it has specific esters that the cylinder liners need. Don't think it's necessary BMW engines but it is very good quality oil.

I run motorcraft in my mustang and have zero complaints.

Using it for 5 years, changing oil avery 8000-10000 kikomiters, enjine souns good (as for disel car)

I have oil analysis done in my TDI and a 10K OCI is a reach. The factory fill was almost depleted of wear additives at 5,500 miles. Fuchs Titan GT-1 was still serviceable at 7,000 miles, but I would not have carried it out beyond that.

and the dealership where it got changed used 5w 20 motocraft they sell ford and thing of tht nature im pretty sure its to thin and wasnt synthetic
