I never worry about oil too much EXCEPT when I'm at the track. I ALWAYS run a 50W then. I always ran the Euro 0W-40 off track because it was easy to get. Anyone who uses 5W-30 or 10W-40 will be just fine. You wont blow your engine up because of it. Yea, you'll reduce your cat life but I bet it will still last 80K miles or more. I never had a cat go bad before 100K miles personally.


Just be sure to ready yourself for the crying. Personally, I dont care.

OK- I've got no business commenting here, but +1 on the Motul 5-40 Gen2 full synthetic. I've been running it for the last couple of years in my lowly 1SS without adverse effects. It's the only brand KTM motorcycles endorses, and they make some pretty amazing high performance engines. It does save some $ and I think Motul makes really good stuff! I doubt they'd let you hurt your ZL1 either!

Oil is oil if you change it often enough, they have to design engine oil for people who refuse to maintain their vehicles and still maintain warranty. I use Amsoil because it’s the most practical accessible oil in my vicinity. I am in the industry of where I have to make everything stupid proof, and it becomes very complicated to make everything stupid proof.

Thanks guys that's is what I wanted to hear
I don't wanted a oil brand Diskussion like bmw M-forum germany for me is that doesn't matter...

Good to hear that ppl are here in a good mood.

I don't have stock cat's anymore I use new gen 1. UHO gesi cats I hope it's working better than my old one HJS

if the car can run 0-40 daily and 15-50 at the track....then 5-40 is totally acceptable...people like to tout manufacturers specs way too often....

my vw gli takes 0-20....the previous gen ran 5-40....the current gen golf r uses 5-30....now why would the golf r with the same engine use 5-30 if the gti/gli are supposed to use 0-20? im glad you asked....it puts out more hp and thus needs a heavier oil to compensate for the heat...same engine...same oil pumps...different turbos and tune...same for the previous gen...same engine...same oil pumps...why does the 18 and older use 5-40? ive actually done about 6 uoa's on different oil weights and brands...and now that im tuned and turbo swapped the manufacturers recommend 0-20 was the worst performing by far....the ONLY reason they are using 0-20 over the previous 5-40 is for efficiency....0w is thinner so the load on the engine is less than a 5-40 oil....

use what brand you want...there are definitely brands that are better than others and have been in the game longer....i wouldnt hesitate for a minute to run 5-40 in my zl1.....jmo....ymmv....

I’ve owned 3 of the Orange bikes and loved them all. There is a reason they got so many Red Bull championships in a row. I wanna say it was 18

I use Amsoil 5W-50 like what the c8 z06 Vette uses after using 0w-40/5w-40. For the first time I actually felt a noticeable difference with the car. Idle is smoother, When beating on the car getting into higher temps the engine just feel healthier at those 6k rpm's.

What kind of oil pressure (hot) are you seeing at idle and wot 5-6k rpm with the 5w50? I want to start running this as well.

thx!
