Which engine oils / spark plugs are best ?

[EXIT]

There seem to be quite a few "high performance" oils available these days and also spark plugs with funky new features, so I was just wondering which engine oils and spark plugs are best for Skylines (and turbo-charged cars in general).

Anyone got any recommendations ?

Cheers,

Castrol GTX3 15w40 is a good cheap performance oil. The cheaper Penrites aren't bad (GP50?).

I dun see the point of using $50+ oil on something that needs to be changed every 5000kay...

Hey dude, I reckon Caltex Havoline 5w-40w Fully synthtic is the shit to run... it costs around $40 for 5 litres, it just depends how much u like your car

yeah i went to autobarn yesterday to choose an oil for my gtst .. theres so much to choose from .. i mean every maker has about 2 or 3 high performance oils ... i'm going to try either the mobile 1 or the castrol .. can't remember what its called ... also heard mutol was good but that was like 80 bucks for 3 litres and it came in a metal can whereas the others came in a plastic one

Exit,

The high performance oils out there are excellent, i.e. Redline,HKS, but at 2-3 times more they aren't worth the money unless your doing circuit racing. In circuit racing a normal oil will start to break down, whereas these oils should still function quite well.

I use Mobil 1 Synthetic, and it seems to be very good. Whatever oil you choose just make sure to change it regularly along with the oil filter.

With spark plugs I wouldn't bother with any of the fancy ones, the factory platnium plugs gapped correctly will be fine, or go for the Iridium ones.

Just my 2c.

i never understood the whole

15w40 and stuff and thats what always confused me when going to buy oil... what do they mean?

[T0nyGTSt]

15 is the cold viscosity.

40 is the hot viscosity.

20w50 is the standard grade for normal N/A engines.

A thin oil is recommended for turbo or new engines (more flow to turbo).

A thicker oil is recommended for older engines (slacker tolerances).

so what are the numbers for rb25det??

[the devil]

I always use Motul oils and have found NGK plugs to be the best...

i love my car, and i believe you love your car too! so use a full synthetic like Motul or the likes.

go to autobarn and get some 5ltr motul 5w40 for $55.99.

also z145 filter..if im nor wrong on the number. z200 for the fuel filter.

I was shown a dyno graph of a 180sx running oldish platinum plugs and standard new 4 dollar plugs and the difference was huge!! (the shitty ones were much better) And then another run with new HKS ones, it was like an extra .5hp. My oppinion is just buy cheapish plugs and change em' every service or second service. Also, platinum plugs should come ready gapped. Never re-gap them, what makes them platinum is a thin layer, if you push in a felar gauge it scrapes it off.

always buy full synthetic stuff, i trust Mobil 1, its about 50 bucks for 5 litres, also try K&N oil filters.

Oil: I use Shell Helix (fully synthetic) 5W-40. It's about $42 for 5 litres and performs really well. Im my experience, It has stayed cleaner than Mobil and Castrol oils, and my car seems just a little smoother with it.

As far as plugs go, just stick with $3-$4 copper plugs NGK-BCPR6E (For RB25), as the only diffence with coppers and Iridium/Platinum plugs is that the coppers dont last as long. But seeing as Skylines run so rich, changing plugs more often is desirable, as you would need to pull your platinum/Iridium plugs out for cleaning every so often.
