Engine oil Shell or RED LINE

Rotella 5w-40, for no other reason than it is good oil that I can use in every internal combustion engine I own, including wet clutches.

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.

Rotella 15w40 for mine. Never an issue and good oil reports for several hundred thousand miles.

Rotella T6 has been good to me.

Shell Rotella T6. It's marketed as heavy diesel oil, but it meets the exact same specs as mobil 1 full synthetic and just has some extra detergent like diesel oils do.

This oil in OG 9-3 that have the crankcase retrofit kits clean the entire engine very well after a few oil changes getting rid of and preventing any sludge issues. The oil even eliminated some nasty tappet noise due to low oil pressure in my 2002 9-3 after a few seconds when I bought it.

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.

Rotella T5, since the T6 is a bit too expensive for a car that leaks. Also a purolator pure one filter. I am up in Northwest NJ. I change it when the HLAs get noisy. It was 4500 miles for the last one.
