| Oil change and filter for an RB26dett engine |
Oil, the engines life blood. In a high performance car like a Nissan Skyline GT-R, it is a good idea to have a regular oil change schedule, and stick to it. Some people say every 3,000 miles, or every 6 months. Some push the changes out to more than that. For any car you are going to run at the track, it is always a good idea to change the oil before and after every track day. Cheap insurance.

| That blue end, that is an oil filter. This is an R32 GT-R |
Oil – The original Nissan specification was 7.5W-30 for the R32, 10-30 for R33 and R34. 4.5 liters in the pan, 0.4 liters in the oil filter.
We now really like a 10w-60 in an RB26. Its been several years now, and I agree with the
Aussies. We have used
Redline 15/50w or 10/30w full synthetic, and 10w-60. We are on
Royal Purple 10w60 now, and seems to be working well for us. 4.5 liters, stock. Filling it to the bump on the dipstick is generally considered acceptable.

Tools – Getting at the oil filter on an R32 GT-R with Hicas can be a trick. It is under the collector. Between the Hicas lines on the frame rail, and the various coolant and air lines under the collector, getting at the oil filter can be a bear. We recommend you buy a 3 claw oil filter wrench.
Sears/Craftsman have them. They are about $15-$20 and will get the oil filter off about 99% of the time on an RB26.
Some people use a screwdriver to stab the filter if they can’t get it off. While it can work, it makes a mess, and if you do it wrong (we have seen it done wrong), you can end up with a nub of a very stuck oil filter.
A strap wrench is possible, but again not a lot of room to swing any tools under the collector. Oil filter pliers, same deal.
In real life all oil filters would be 1/4 turn past hand tight, but even then they can still be difficult to take off.
The K&N HP 2008 oil filter has a 1″ nut on the end that makes removal a bit easier. It also has a provision to safety wire the filter in place. Most people wouldn’t safety wire/lock wire their filter in place, but in the race world, it is a great idea.

| Trust oil cooler kit with oil filter relocated in front of subframe. Not our favorite place to put an oil cooler |
Other Options – An oil filter relocation kit is a popular way to make oil changes a little easier. There are a number of ways of doing it. If you are putting a relocator, we highly recommend an oil cooler at the same time. The OEM filter is a 3/4-16 thread. Some oil filter relocations change the filter thread pitch, so make sure you check the instructions before you buy a gross of oil filters.
