Engine oil Shell or Motorcraft

I’ve been using t6 with pretty good lab analysis but I’ve been considering switching over to amsoil.

Since getting my tune I run Rotella T6 5w-40

Walmart. Shell Rotella 5qt for $20. Or Mobil1 for less than $25 if they're out of the Shell and K&N filters always in stock.

Anything is better than nothing. I've tried most big oil brands but overall I like the Shell Rotella stuff most.

I use the T6 as well and like it a lot. Other people in this forum have recommended in the past as it’s additives are supposed to be good the 4.0’s. Always worked well for me, it’s reputable, not the most expensive and if the additives do actually help, thats only ever a good thing.

Can't go wrong with [Shell Rotella T6](https://rotella.shell.com/en_us/products/full-synthetic-and-blend-oil/t6-full-synthetic.html). Full synthetic, JASO-MA certified and cheap.

Shell Rottela 5W-40 full syn.

new filter and oil (Rotella T6 highly recommended)

Shell Rotella T6 will change your life on n54

I’ve been using “Rotella-T 15w-40” (non synthetic) in my 2005 Honda Shadow Spirit VT1100C since I bought it used in 2006. It’s a fine oil.
