Hey guys.

 

I'm wondering what the best engine oil is for K motors. I've got a 5K and I'm planning on changing the oil today. I usually use Caltex Havoline multigrade 20W/50. It seems alright but I can't help but wonder if there's something better out there.. so what does everyone else use?

 

Cheers.

Penzoil 25/60, high mileage, works fine in my old 3k...

I use Shell 20W/50 in my K.

 

I went chasing what oil to put in my 911, and when I found the factory specs for that were 20W50 I figured its good enough for a K engine!

20W/50 is always the way to go.

As for the brand, anything but home brand would be fine i reckon.

but penzoil is definitely up the ranks as one of the best :yes:

So I'm sticking with 20W/50 it looks like. :yes: I guess brand-wise it doesn't really matter then?

 

Cheers guys.

i use castrol gtx or gtx2, never had any problems n its 20/50

I use mobil 1 synthetic in the 4AGE which is 5W - 30, though I think you can get different rates in it now.

 

For the 3TG I will use a 20w 50 preferably something from Penrite. I swear by Penrite from my old 2T days.

My 4k runs really well on Penrite HPR30 Which is a 15w60.

My 4k runs really well on Penrite HPR30 Which is a 15w60.

 

 

And that is what I will be using!

Penrite HPR30 all the way!

HPR 30 is actually 20W60.

They recommend it for older engines, expensive for a young bloke like me though. :locked:

motul 15w50 cost 60 at autobarn, 4k runs really nice on this :locked:

Yeah, my Bad got em mixed up. I use the HPR 15

I've got a 3k (I think? 60 bhp or something), I usually fill it up with the most simple 10w-40 or 5w-40 I can find. I occasionally fill, the two last times it's been dry. Approaching 300k km :D
