as above really, gonna change the oil in me RS2K's

do i want part synthetic?

also does i really matter if i use 10-40 or 5-30?

as halfrauds selling 10-40 @ £8.99 for 5L
or 5-30 @ £18.99 for 5L

sorry for bein so stupid but i always get confused when it comes to oil

 

10w40 full...
good brands only!! (castrol, mobil, shell...)

 

go 5w 30 if the engines over 100k

 

rseb whys that mate i thought 5w 30 was thinner than 10w 40
my cars done 125000 and i use any shell 10w 40 in it rattles when cold but is dead quiet when warm

 

saint: you r right, it is thinner...

if it rattles when cold like that, then i would recomend 15w50... full sintetic again and always!! will help you with those "strange noises"...

good luck

 

i used to use 15w 50 in my cossie and was a good oil but i just thought that was to much for the rs2k but i`m up for tring anything lol

I made the big mistake of engine flushing the car about 3000 ago hense why she makes some noise when cold............

 

yeah sorry monging it

 

ive just put 5w 30 in my RS2K its quietened the tappets

 

10w 40 Castrol magnatec if under 100,000
You need nothing else

 

The correct oil is 5w 30 as recommended by my ford dealer when i had mine as it's the correct oil for the i4 engine mate, cheers, Grant.

 

Semi synthetic 5w 30 is the one to use for the RS2K

 

I would have to agree with these guys, I have 5w 30 in mine, quiet as a mouse and only 57k miles
