Amsoil

 

Which one? I'm using Amsoil in a small block and very happy with it but it took me a while to figure out which grade was best.

10-40 synthetic with zinc
However - I do not run any cats so the zinc is good for me

 

Same with me, the 10-40. AMO is the product code. Bad on cats, GOOD for bearings and engine longevity

 

it appears LN engineering is recommending Joe Gibbs DT40 rather than Motul 300v now..

anyone try these?

 

I am running Joe Gibbs Driven DT 40 which I purchased from LN Engineering. I have a great deal of respect for the objectivity and analysis LN brings to the table and am particularly impressed with the way this oil holds up under high temperatures and stress loads. It's expensive but compared to the cost of a motor, not so much. Check out the links I posted above if you haven't already done so. Best,

 

We run Pentosin/Pento High and Lubro Moly / Liqui Moly

 

Mobil 1
TD 5/40

 

I like:

For oil- olive oil
For detergent- washing up liquid
For wear- sewn on elbow patches
For ash reducing- a dust pan
For anti-oxidants- cranberries

And that's about as much use as most of the speculation here. It only proves the hype/marketing has worked.

My last oil change was done with Mobil 1 5-40 TD. Nothing has let go so far....

 

Mine has had factory Mobil since new and has covered 78,000kms without any issues and it doesn't exactly get driven like a nanna.
Mind you I do change oil every 5k.

 

That's the best advice, frequent oil changes!

We use Motul and Lubro Moly

 

Just got back from dealer, they said Mobil1 5W-50 is the latest recommendation for GT3s here in Switzerland. I've been using Mobil1 5W-40 until now.
