Simple question

Dan - Did you do a search or read your owners manual? This question has been discussed, rediscussed and re-rediscussed. As long as the viscosity is somewhere in the neighborhood of 5w-30w and you keep it changed and use good filters, there has been no discernable differences in engine wear between different motor oils.
Yes, I'm sure it has. And I did search the archives with NOTHING coming up. (Very strange) And no, I haven't checked my manual... too damn busy with everything else and I figured throwing a quick question out there would be faster than me finding my book, then finding the specs. I can't remember where my FSM is anyway. LOL!!! It's buried here somewhere!!! 
I'm a Mobil 1 Full synthetic man myself. I believe I use 10w30. I also believe it takes 5 quarts. My service guy (who is an NSX guy) over fills all the time by like a quarter to half a quart. I checked the oil once noticing it was over full, called him and he told me it's just fine.
for me, the best oil is the synthetic 10W30 because the engine (already more than 20 years) was planned for this viscosity, with oil 0 or 5W, there will be risks of escapes, the joints (gasket) are planned for an oil of 10W minimum :smile:
To the OP: the search function of NSXPrime doesn’t let you search for terms with three letters or less – like “oil”. Try searching for something related that has more letters, like “viscosity”.
To Thunder: You shouldn’t rev your engine high or use lots of throttle before the oil is up to normal operating temperature, right? Before the oil is fully warmed up, it doesn’t flow through the oil passages at the speed it should and doesn’t build up the film thickness in the bearings that Honda’s engineers wanted. When it’s up to normal operating temperature, all is good. Before then, be careful.
On engine oil labels, the number after the W indicates how thick the oil is at normal operating temperature. Oils that have a viscosity of about 10-12 cST at 100°C are labeled somethingW-30. The number before the W indicates how thick the oil is at cooler temperatures. Oils thicken as they cool. The lower the number before the W, the less they thicken as they cool. The specs of some Amsoil oils show this quite well:
AMSOIL 0W-30: 57.3 cST @ 40°C, 11.3 cST @ 100°C
AMSOIL 5W-30: 59.5 cST @ 40°C, 11.7 cST @ 100°C
AMSOIL 10W-30: 66.1 cST @ 40°C, 11.7 cST @ 100°C
A 0W-30 oil isn’t too thin at startup. It’s just not as much too thick.

I actually searched "oil change" and "oil recommendation" "recommended oil" and nothing came up.
Strange. When I type in "oil", I get nothing. When I type in "oil change", I get 250 results - the maximum that the search function returns.
In any case, good luck with your decision.

I thought it was strange too. No idea why it didn't work last night.
I found my FSM last night too, so my questions are answered. Thanks!

I prefer AMSOIL. 10W-30
my car has 170.000 km, never escape, in 2010, I replaced my usual oil by oil 5W30 ... to see… 
I have an escape with the casing has oil 
, this year, I will replace the gasket and will replace 5W30 by new oil 10W30 :smile: I think that it's better :smile:
