Engine oil RED LINE or MOTUL

My first service after purchasing my Harley, I used SYN3 in all three, since then I’ve religiously used REDLINE kits.

Have been using Motul 5w30 for many years now...

Dt 40… also use motul xcess gen 2 in the 986, the cayenne and a couple of bimmers. Blackstone reports look g great with all of them.

I’ve used Motul, LiquiMoly, Molygen, and Redline 5w40. Oil analysis was best with the Redline, but it’s pricey…although worth the better numbers IMO.

I use Redline 5w-40 because I noticed my engine burns a quart every 2000miles using other brands or thinner grades. With RedLine there is barely any consumption.

I use Motul 8100 EcoLite in mine. Paired with the appropriate Motul fluids in the trans and diff, and RBF660 in the brake lines.

Motul 5W-30.

I'm running 10w60 MOTUL 7100, I sit on the revs though, always Tach out!

I recommend Motul and I advise tou to never use RS8, it's a rebarded Xhina brand.

I do have slight oil loss but I also track my car several times a year so it's to be expected. Recently switched to 5w-40 motul so we'll see how that does.
