I use red line 10w30. Even though it says recomended oil change in 12-15k miles, I change it at 3-4k. You can tell me Im wasting money, but I just have a deep love for my motors.

I've been using redline in my KA for 3 changes now and everytime i change it (3k first 2, 5k the last one) it's been black as hell. But when I go to fill it up again almost ALL the varnish I could see before is gone now. Ima keep using it and maybe down the line I'll do some UOA's.

Its good stuff. I buy it in 12qt cases off ebay for $70 shipped so its not that bad on $. Also royal purple has about the same deals, maybe 5-10 $ cheaper, but are just as good.

I use Mobil 1 full synthetic, 10w 30, get it at Wal Mart for 19.82 regular price or for 17.88 on sale.

3000 miles or every 3 months. i've put maybe 500 miles on the car in the last 5 months so when it gets outta the shop it'll get all lubed up.

you dont have to change it at 3k (That # was made up by the manufactures in order to produce more income for dealerships) Oil is actually good for more like 4-6k depending on your driving habits. (In the case of drifting I would change every 3k or when ever the oil becomes black. (If Synthetics used you can put off changing a little longer)

Phlip

Actually that number was made by the MANUFACTURER (I believe Nissan set it at 3500 miles?) so they wouldn't lose their ass on warranty claims for stubborn people who would SURELY stretch that a few hundred miles, all while driving the HELL out of their cars... Now take us, as enthusiasts, who drive the DOORS off of our 100/125/150/200k + mile cars and are more than capable of changing the oil ourselves, it would be just plain dumb to NOT change the oil at 3000 miles... "better to have and not need than to need and not have" the old saying goes

Mobil 1 Synth changed every 2500 miles, or when I burn through a set of Falken RT-215s. Whichever comes first.

With synthetic oil you really shouldn't need to change it more than every 4000-5000 miles unless you are really beating on it. I think Bill is on target with checking the color.

^^^ Leaving out the times with which the EXTREMELY anal-retentive will use to change theirs, like the ones who are prepared months in advance for an oil change?

Lots of folks change oil every 3K or 3 months.. it's what the oil manufacturers have spouted for years and years and it's become the way you're "supposed" to care for your car. This is a lie..

The detergents in regular oil really have very little to do, IF you run your car till it's completely warmed up (like a long trip on the freeway) once a month. The oil will trap the contaminates and they will disipate with heat.

Oil changes depend on load, and type of driving. IF you are driving stop light to stop light, going to the grocery store, the post office.. etc. and never driving it out on the freeway or ever getting it fully warmed up, the 3000 mile rule is a GOOD one. IF you are driving the crap out of your car, getting the engine up to full operating temperature OFTEN, then 6 - 9K between oil changes isn't gonna make a whole hill of beans difference in how long your engine lasts.

As for the color of the oil.. clean oil is a GOOD thing, but just because it turns a little brown doesn't mean it's life is over.. of course if it's black and sludgy that's another story. As long as the oil still flows freely, and doesn't stink to high heaven it's probably ok..

Drifting is tough on rear ends, and tires and suspensions, but high engine RPM and heat in the engine is a GOOD thing (to a point), it burns off most of the contaminates from burned and unburned fuel in the oil, and what doesn't get burned off gets trapped in the filter. Engine wear isn't the biggest issue. Neither is the type of oil you use.

You are going to wear out your entire suspension, tires and differentials LONG before you're gonna wear out your engine. Synthetic oils will make your engines last longer.. but what is the point? The car is gonna be trash LONG before you can wear out your engine doing regular maintenance and using conventional oils.

i change mine at 3,000, because i do city driving and aone every two weeks i go do a canyon run or 5.

mr_240sx

well im from canada so i change mine every 5000Km.

what filter does everyone use? I always use the Fram ones just because they are always right there... but what's actually a good one?

I've been using mobil1 synthetic on my RB for a while and i've noticed it turns black really quick and my engine kinda eats the oil fairly quick

I'm sorry but oil temps and the type of oil you use are very important when it comes to drifting. Redlining your car non-stop in 100 degree weather causes underhood temps and oil temps to soar. A synthetic oil will resist thermal breakdown and will cause your engine to wear much less than a non-synthetic that got burned to shit in a single day of racing. On a turboed car, this is especially important, even on a daily driver that doesn't get track duty.

My oil gets changed with mobil1 15w-50 every 1000-2000 miles due to track duty.

I change my filter every 2000-4000 miles using a mobil 1 filter.

One of the next things on my list of things to buy is an oil cooler to help prolong the life of my oil and to keep the engine cooler.

i used mobil 1 before.... and i changed it every 3000... but i figure that using castrol gtx and changing it every 2000 mile might be better (cleaner oil cause less miles) and it's cheaper than mobil 1.

what do you guys think???

'90 S13 110k mi, 10w40 (dino/conventional valvoline, chevron, mobile), amsoil filter. Daily driving.

1st change: 3500 miles / UOA indicates drain interval can be extended, sufficient TBN levels remain. Insoluables level normal.

2nd change: 5000 miles / UOA indicates drain interval can be extended, sufficient TBN levels remain. Insoluables level normal.

I'm trying 6000 and 7500 miles next. The oil changing color is not necessarily an indication of an oil change being required... if anything, it means the oil is doing its job- cleaning. Oil is still good if the level of active cleaning agent(s) is sufficient, the filter is keeping the level of insoluables low, and the viscosity level is within an acceptable range.

i changed mine every 2k miles. i dunno why. but i will continue to do so
