Valvoline Durablend 5w30. Do you guys I can switch to a full synthetic now at 75k miles? I switched to the part-synthetic at less than 60k.
Thanks,

Mobil 1 10W-30 year round

Used Castrol GTX 5W30 for break in period.
At 7000 miles switched to Mobil1 5W30.

Mobil 1 supersync 5w30

Still going through the break-in period. I use Castrol GTX 5W-30.

Mobile 1 5W30

Mobil 1 5w-30 Supersyn w/ Nissan OEM Filter

Penzoil 5 and 10-30

Just put in Castrol Syntec synthetic blend if anyone even cares

I've heard to stay away from synthetic blends

I would always use an original Nissan oil filter. The factory oil filter is very good. I've read twos article a while ago showing that FRAM filters are cheaply built (cardboard) ends etc.

One of the articles is here: FRAM Filter Tests

You're free to use what you please. Just thought you might want to know about this body of knowledge out there.

Just hit 20k miles and have switched to Mobil 1
supersyn 5w-30, plan on getting 5-7 k per oil change.

castrol full synthetic 5w40 euro car oil....used to run syntech but ... I have a half a qt left after every TDI oil change (I'm a VW tech) so I net a free qt of synthetic every other TDI oil change
and the oil meets all requirements for MB/VW/Porsche/BMW gas eng .....should be A-OK for Nissan

Castrol GTX 5W30

what's the benefit of 10w-30 over 5w-30? I know 5w lasts better in cold...

I been using bmw 5w-30 synthetic because my friend work bmw service, so I get for really cheap. I woundering is it safe. it don't have a mark for API certification but, the API SAE service grade is SJ 5W-30, energy 1.

5 W weight oil is a little thinner, meaning it flows better when cold, other than that it works same as 10 W

Mobil 1 5w-30

Switching to Mobil1 SuperSyn (Motul if I can find it) 5w-30 w/ Nissan OEM filter this weekend!

ok I only have 56K on my car and use Castrol FULL SYNTHETIC, should I change for the winter?

5-30 is thinner oil with more synthetic stuff added. theoretically, it loses viscosity earlier due to shear.

I use 10-30 dino oil. V or Q or P or M on the bottle, doesn't matter.

Penzoil 10w-30, every 3k miles. Used to Mobil 1 but so expensive for a quart

5w30 Castrol GTX with OEM 9e000 Filter

I went from mobil 1 ss 5w/30 with nissan filter to castrol full synthetic 10w/30 with toyota filter. This was best decision made for my car. The ticking has pretty much disappeared on my max and I've noticed that the oil is more honey color.

Definitely recommended for the ticking in your car.
