Engine oil RED LINE or Motorcraft

I use Redline 10w60.

I’ve been using redline in my 2020 fxlrs for the last 3 years. A few guys I know swear by it.

So far redline 20w60 is doing great in the summer heat

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

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 run Red Line oils in my H-Ds and Indian.

Get the Redline 5W-30…you won’t be disappointed. I was floored by how much better my Z performed with this oil. I’ll never use anything else.

I have the 6.4 liter Hemi in my Charger, and I switched from Ultra Platinum to Redline. My car uses 0w 40, but nonetheless, I have not seen or felt any difference between the 2. If you are worried about switching, I can assure you that Redline is a very high quality oil.

I've tested both those oils, and was not impressed with the results. Both oils still needed changing at 5k.
