Hey guys,

Just bought a 09 Frontier with 52k miles. Had a few routine service questions coming up.

1. What brand oil and filter do you all use in these trucks?
2. I was going to do a radiator coolant change and wanted to know what is the proper type and how much?
3. Do I need to do any other fluid changes for the 60k service?

1. I use whatever the monthly special oil/filter combo is at the auto parts stores, however synthetic blend is OEM.
2. Any "OAT" type coolant, color match not required. I used Peak 50/50.
3. *highly* recommend a drain and fill on auto trans oil at 60k. Castrol Transmax Import/multi

Additional
Rear diff oil change 75w90
if 4x4 transfer case
bleed brakes to flush through old fluid

I don't quite remember and would have to check the manual but think that the previous post sounds right.

I kind of remember that 60k wasn't as big of a service as I expected. But some other fluids you might want to consider are transmission fluid and differential fluid. Will try to take a look at the manual when I get a chance.

Searching on the forums I found some posts on here that said that Pentostin A3 is what Nissan uses and just rebadges as their coolant. They're both blue. And actually your 2009 might have come with the green coolant which is equivalent to the A2. Somewhere along the line Nissan changed the coolant from green to blue. Blue is supposed to be backwards compatible and you can use it either way. Some people wonder if the change in fluid is partially due to the cross contamination issue.

A lot of people use Prestone 50/50 for coolant as well. I got kind of paranoid when I saw that it was clear and didn't match either color of coolant and returned it. But then later found out that the color of coolants is really just a dye to identify the different coolants and Prestone just didn't color theirs. (based on threads on the internet, don't know how true it is)

For oil/oil filter that can be based on personal preference. You can check the bobistheoilguy site too for oils and filters if you don't have a preference or something you normally use. A lot of people have good things about Mobil 1 and I'm thinking about switching to that, mainly because I'm driving more miles now and want more time between oil changes.

The coolant change had nothing to do with the cross-contamination issue, which is caused by a seal failure in the radiator's integral cooler. Both of Nissan's coolants are made by Pentosin: Nissan green is Pentosin Pentafrost A2 and comes as a concentrate, while Nissan blue is Pentafrost A3 and comes in as a pre-mix. Both are long-life coolants, but, blue is, for lack of a better term, a "longer life" coolant. Nissan green is recommended to be serviced at 90,000 miles and then at 60,000 miles, thereafter. Nissan blue's service interval is at 150,000 miles. While the two are compatible, one has to remember that any green coolant mixed in with the blue coolant will shorten the blue's 150,000 miles service interval accordingly. Nissan started incorporating blue coolant in it's vehicles in 2010. Pentosin anti-freeze can be purchased from Rockauto.com, Amazon and found on Ebay. With a 2009, one might also consider replacing the radiator and the coolant, if the radiator is the factory-installed unit and the truck has an automatic transmission.
Engine oil and filter are always highly debated as everybody has their own preference. I've always stuck with genuine Nissan oil filters, but go with Purolator Pure One filters in a pinch. Purolator makes a large number of the filters on the market, including Bosch, Motorcraft, Pronto and many others. AC Delco makes an excellent filter, as does K&N, Wix, Mahle. I've never been a big fan of STP filters nor Fram, due to their construction...but, I've never ran into any problems with either of them. Engine oil is equally debatable. Most will agree, including myself, that 5W30, as recommended by Nissan, is the best to stick with. I know on some of the newer Nissans, they are calling for 0W20 synthetic, but, also go on to say that 5W30 conventional can be used as an alternative and will not void warranty. Blackstone Labs, who does oil analyzing, states that their employees all use conventional oil, which says something. I don't think there is any argument that synthetic oil is better than conventional oil, but, is it really needed in or provide any real benefits to the majority of the vehicles on the road? I think the bottom line is that oil quality these days is very good and any API certified 5W30 will work just fine provided that is is serviced at the proper intervals. Personally, I use Walmart's Supertech 5W30 full-synthetic at 7500 mile intervals. I had a sample tested by Blackstone Labs (when my engine reached 150,000 miles) and they recommended extended my intervals to 9500 miles.
I do a drain and fill of the automatic transmission fluid and transfer case fluid at 50,000 mile intervals, using Valvoline Maxlife ATF. Castrol Transmax Multi-import ATF is also a good choice and both are a lot less expensive than NissanMatic "J" or "S" ATF and work just as well. Most synthetic ATF's are JASO-A1 compliant and will work fine in the Nissan 5-speed, rear-drive automatic transmission; just make sure it says it is recommended for use in NissanMatic "S" or "J" applications.
I service the front and rear diffs every 60,000 miles using synthetic 75W90, either Mobil One or Supertech.
The engine oil drain plug and transmission drain plug use copper crush washers, Nissan #11026-01M02, which you can buy in bulk on Ebay in bags of 5, 10, 20, 50, etc.
The transfer case and differential fill and drain plugs use aluminum crush washers, Nissan #11026-4N200.
Don't forget your cabin filters behind the glove box!

Check the manual it has it all in there. You can also download them online if you didnt get one. Use whatever oil you like. Everyone will give you a different opinion.

But they are wrong unless they tell you Pennzoil Platinum!
