No not the oil filters, just the fuel filters
You don't have to. But I put oil in them when I can. Just the way I was told to do it when I first started working on engines.
Change oil and filters regularly
Probably Wix.
Made in China !
Air filter, oil filter, petrol or diesel filter.
If the oil filter bypass is not able to work properly then yes.
Every other oil change
You need to be specific as to engine type (diesel or petrol, and then which size or type of diesel or petrol), and also quote year and/or Mk number. All have different sump plugs, oil filters and so on.
In 1997, Ford Fiestas were manufactured with a variety of different petrol engines and a diesel option. All have different oil filters.
Every 4000 miles. Change it when oil is changed, along with oil filters
Just changed my oil today. 12v71ti marine engine. New Filters, 9 Gallons of Rotella T1 40w
Yes as it does not have the lubrication of diesel. Also may damage fuel filter. Don't drive. Get quotes to clean out tank, filters etc but if you want to risk it and tank is not full you can fill with diesel and then run engine to use petrol/diesel mix. Get tank emptied by mechanic for safety. Change filters soon afterwards .
Depends on which engine is fitted - the Mk 6 was produced with a choice of petrol and diesel engines - All have different oil filters.
