Engine oil Shell or IDEMITSU

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.

Idemitsu is the only premix and engine oil I’ll use ... you can order it for a good price from TREx performance out of NJ and he will ship

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.

T6 is great motorcycle oil I've used it often.
