infinti recommend 5w 30, but i've heard that in warmer climates you should use 10w 30. what brand and kind of oil do all you use?

 

you don't want it too thick.

anyway, i use mobil 1 synthetic 5w 30 with oem, or mobil 1 filters.

 

think honey
warmer =thinner
10w30 would be fine were you are
I use Royal Purple.

 

I use amsoil 5w30 and honda oil filters...serious! the one thing I like about the honda oil filters are that they have more filtering capacity. been playing around with the weights, with 5w30, the engine revs quicker..with 15w30, I gain a little torque. Mileage all seem to be the same.

 

NO HOMO. thanks for the typo clarification.

 

5w30 and 10w30 are the same viscosity when hot (Where the "30" part comes into play). When cold, one is a 5w (Winter rating, not w as in "weight") and the other is 10w. All things being equal, I would run 10w30 if you're in a warm climate. Reason being, the closer the two numbers are together the fewer VIs (Viscosity Improvers) are required to attain that viscosity spread which means there's less chance of viscosity breakdown.

Once up to operating temperature, both the 5w30 and 10w30 have the same viscosity.

 

um... i'm still not sure which to use. can i get in trouble from infiniti by using 10w30? and synthetic?

 

no, but once you go synthetic, don't go back to non-syn.

just run the 5w 30 is my recommendation.

 

thanks, maybe i shouldn't go synthetic yet, i only have 5xxx miles

The best non-syn oil I've used is Castrol GTX; in an independant study by Sport Rider magazine, they concluded that the GTX is the most comparable non-syn oil towards the synthetic versions.

The best Synthetic Oil I've used is Amsoil. I tried Royal Purple, Torco and, Redline...they're all good synthetics..but I believe they're synthetic blends...not pure synthetic like Amsoil - I could be wrong though.

Oil Filters, so far...I like using Honda's filter. Im not too sure on the model it's supposed to be used on...but I saw a picture of the Falken G35 with a Honda oil filter and I thought that was good idea. after evaluating the size between the Nissan and Honda oil filter, the Honda oil filter is longer, thus having more filtering area. You could always buy one of those expensive stainless steel element filters, that are reusable. from what I read, they filter out things better. I think they're like $100 or something...I have something similar on my motorcycle, and its worth it. I may be looking to getting one for the car.

It's all in preference, the one thing that should be more pressed than just choice of oil is, frequency of oil change.

 

You can go synthetic already if you want. I went with synthetic at 8k.

 

I use 10w30 mobil 1. In the service maual it states 10w30 is ok for warmer climates.

 

Old wive's tale. Modern engines, synthetics and seals have no problem with either one, you can switch back to conventional without any ill effects.

 

ok thanks guys
