Post 5w-30 vs. 10w-30 oil

I want to know which is the best weight of oil to use for the 02 SE-R. In the manual they prefer 5w-30 for all weather. I have been using 10w-30/40 since i have had the car, I have 48k miles now. I was told that using 5w-30 gives you a little more power cuz its not so thick. HELP? I need to change my oil this weekend.

I dunno about that one. But I was thinking of that as well. I dont really think there is a major difference between the two except for the freezing temp, if any one knows share the knowledge.

If you use synthetic it won't matter at all. If you use regular dino oil it only matters if you live in extreme temps.

passing on Al's wisdom:

as far as performance goes, there's no difference between 5w30 and 10w30.. when the oil's warmed up, they are both the same weight (30). 5 and 10 is what they start out at cold.

Now, the reason I use 10w30 over 5w30 is that 10w30 has less friction modifiers (i think) which means it holds up better. I would use 5w30 if i lived in a colder climate (i.e. 0 degree winters).

hope this helps

5W30 is generaly the best formulation all year round for our SpecVs since they are new cars, until they reach high mileage. I will personnaly use 5W30 up to 100 000 km (62 500 miles) and then switch to 10W30 for summer and 5W30 for winter.

By the way, I live in Montreal, Canada (crazy winters).

The friction modifiers is only true for regular dino oils. In order to get the numbers apart they add polymers. FOr regular dyno oils, you get few additives the closer the numbers are together. That is also why 5w30 is a little more expensive. Synthetic is all the same.

I called the Nissan dealership today and was told that 5w-30 oil is used for the 02-05 Nissan SE-R's.
