I've always just used GTX 20W50,

recently had a service and Nulon 20W50 was put in.

Its all got me thinking about oils; as I had to top up my Tiguan by 250ml before it's first service.

anyway, been looking into the Castol Edge range (as recommended/manufactured by VW as well) and thought about putting in some 10W60 or 5W30 Castrol Edge.

Has anyone used these weights of oil before?
What oil weight do most of you use? (i'm guessing 20W50)

As I see it, it will warm up quicker and stand hotter temps better than a 50 weight....

Further to this VW recommends in the orignal manuals to use a straight SAE 30 (like ACE30), and for colder use recommends a SAE 10, so could one safely assume if a 10W30 or 5W30 was used that it would be more suitable than a 20W50 for all climates?

interested in your thoughts

**Should note, my engine is a 1300 in a beetle only used now for 'racing'**

I have always used CASTROL GTX 2 in My beetle...

for ordinary road use.... not on a private race track... lol

for racing the Castrol edge would be the pick...

although many people on here will pick a different oil... lol


IS the beetle engine standard????

If it is I would still go with GTX2...

If it has extra cooling then I'd go with a lower number like
5w/40 maybe... ????

My brain still thinks that I should use 20W/60 oil as its thicker
and shouldn't go as watery [thinner] when really hot..???

but I'm still using Castrol GTX 2.. 20w /50 oil...

I use Castrol Magnatec in My liquid cooled cars...

The thing you have to be carefull of going too thick with the oil is the higher pressure causes the releife valve to stay open and bypass the oil cooler which leads to high oil temps, although its more of an issue in duel reliefe blocks.

I only ever ran old shitter engines on 20/50, fresh ones ran fine for me all year round on 10/30 or 10/40

yeah i have heard good and bad about castol edge
im not sure if ace 30 is a mono oil??
anyone avea used golf westen oil in a aircooled i know they have a cheap 20/50 xmp but then they have a good 20/50 as well
i can buy it in 20L for a good price anyone know what it's like?
but yeah in an oil ish donk it wont make much difference

omg castrol

I only use ACE now and since from when it was available.

You need oil with zinc additive for protection, I only use Penrite Classic HPR40

that is true about a zinc additive i think for lifters
but ace is very high in zinc
but carn't you buy zinc additive on it's own and add it?

I use Castrol Edge with Liquimoly added.....never had a prob, and I'm not gentle on my motors

ACE 30 is 20W-40 multigrade, ACE 40 is 25W-50
