I'm looking to do the small service on my 2016 290 Cupra ST, It was meant to be serviced late last year but due to Covid I am been working from home the past year and not using the car at all... like twice a month to just give it a run. So I was in no rush to service it as the oil also looks clean still.
I'm looking to use 5-30w but noticed that you have a choice of long life oil which says to be changed every 2 years?
Oil Link Castrol site
Which one do people use? Normal or long life?
Also read that mk3 are using plastic sump plugs, just checking before I order bits, and it's to dam cold to climb under my to check right now.
Cheers
LL oil is VW 507.00 spec and was meant for those lovely 20,000 mile services. I would never leave oil in a car that long. I use LL 507.00 but change it every 5,000 miles. Car prefers it and as mine is diesel (DPF) I think it's worthwhile.
Just check but I think you can use either. As you have a Cupra I'm sure someone else can give you a more specific answer.
As for sump plugs. My 2014 uses a metal/alloy one. I believe that post-FL use the plastic one.
