today I went shopping for new oil. I wanted grp 5 syn. and liquimoly is only 3+.

at walmart right now Pennzoil 5w30 grp 5 100% syn 4.73 ltr is on promo sale $28.88

I bought 3 for under $100 ( 4.73 ltr x 3 = 14.19 ltr = 4.05 oil changes = $25 an oil change for grp 5 100%syn )

now I don't generally like fram filters, but this ultra syn filter looks pretty neat

"xx"-6607 is the filter number for the hr16de. the "xx" varies depending on the type of filter from "ph, xg, etc."

it looks tiny but is also used on the turbo juke and even the 3.5 ltr Nissan engines so should be fine. but costs $13.xx still ... under $100 for full syn changed twice a year is not bad. I use to pay $120 per change in my skyline.
