I've been part time at Autobarn since high school, i've owned my skyline since highschool and im studying mechanical engineering, so they can't all be that bad :)

But seriously back to SuperS13's question, fully synthetic oils are 100% fine to use in a daily driven car. I've used it in mine for ages (owned it for 3 years and only ever ran 300V chrono or 4100 turbolight in it, depending how tight cash was. Now only ever run 300V) and its 100% fine and when i took the head off everything looked like new including all the bores. No need to treat the car any differently. Warm up times and shit have more to do with the viscosity then whether its a full synthetic or semi synthetic.

At the end of the day i always tell customers this. There is no one certain oil that can cover every single car, every climate and every use that the car is going to be treated too. For 90% of people an average off the shelf 10W40 or 20W50 oil (regardless of brand) will do the job. It's better to get the viscosity right for the climate and mileage on the car then it is for a specific brand of oil.

If you however can spend the extra money on a well branded oil such as 300V, redline, mobil 1, royal purple etc. Then honestly for a street driven car, you will never outperform above what the oil is capable off.

Hope that kind of made sense.

You sir are a champ. Cheers for the info

Waiting on Call for Drum or Drums of Chrono & price. Might have to open a Motul Store here in Newy LOL.

Im down for group buy.

Anyone know the shelf life for opened oil?? id expect it to be long, perhaps over 2years.

Do you guys think it's worth the extra $10 or so on a Greddy/K&N Oil filter as opposed to a Ryco or Nissan OEM oil filter?

Buy a drift one, better than both. i have some weak check stats somewhere comparing particulate size and the drift one came up very well.. i will see if i can find it.

oh and if anyone is in melb and want cheap MOTUL i usually stock about 3-4k of the stuff atany time and will beat any price, especially if your a regular :laugh: i supply the melb s15 club etc..

I actually used to get the Greddy ones through work for the same price as the Rycos lol. If you don't mind spending the extra dollars on a K&N/Greddy then get one. As far as im aware no tests have been done (read "proved") that one is better then the other.

I just got a 4 and 2litre bottle of 300v and a drift filter from Autobarn, they had a whole range of Drift filters there and Royal Purple oil aswell.

After reading all the info on oil base stock. I now only use 300v 10w40.

The API groups oils into five major categories, each with different properties and production methods:

Group I: Solvent frozen mineral oil. This is the least processed of all oils on the market today and is typically used in nonautomotive applications, though some of it may find its way into low-cost motor oils.

Group II: Hydro-processed and refined mineral oil. This is the most common of all petroleum oils and is the standard component of most petroleum-based automotive and motorcycle engine oils.

Group III (now called synthetic): The oils start as standard Group I oils and are processed to remove impurities, resulting in a more heat-stable compound than possible as a standard Group I or II oil. Some examples are Castrol Syntec automotive oil and Motorex Top Speed. These are the lowest cost synthetics to produce, and generally do not perform as well as Group IV or V oils.

Group IV: Polyalphaolefin, commonly called PAOs. These are the most common of the full synthetic oils, and usually offer big improvements in heat and overall stability when compared to Group III oils. They are produced in mass quantities and are reasonably inexpensive for full-synthetic oils. Since they are wax-free they offer high viscosity indexes (low temperature pour point) and often require little or no viscosity modifiers. Examples include Amsoil and Motorex Power Synt.

Group V: Esters. These oils start their life as plant or animal bases called fatty acids. They are then converted via a chemical reaction into esters or diesters which are then used as base stocks. Esters are polar, which means they act like a magnet and actually cling to metals. This supposedly offers much better protection on metal-to-metal surfaces than conventional PAOs, which do not have this polar effect. These base stock oils also act as a good solvent inside the engine, translating into cleaner operation. Esters are the most expensive to produce, and oils manufactured with them usually cost much more. Due to this higher cost, many companies only fortify their oils with esters. Some examples are Bel-Ray EXS, Torco MPZ Synthetic and Maxum 4 Extra. Motul 300V, however, uses 100 percent ester as its base oil, and is one of the more expensive oils.

The grouping of these oils is the source of much controversy. One topic that has been debated is what can be labeled a "full synthetic oil." In 1999, Mobil brought a complaint against Castrol for changing the base oil in its Syntec product. They had used a Group IV PAO, but had changed to a Group III base oil. Mobil contended that Group III oils were not really "synthetic oil" and should not be labeled as such. After many expert opinions were heard, the National Advertising Division of the Better Business Bureau sided with Castrol and said that Group III oils could be labeled synthetic. Since that time there has been a lot of growth in this product type due to its low cost and similar performance to traditional synthetics. Many traditionalists still argue that Group III oils are not true synthetic oils.

At the end of the day if you are dropping your oil every 5000kms it doesn't really matter what filter you use, they are all pretty much going to do the same thing in that short a time.

Purolator are very good too. K&N and the DRIFT ones both have a lug nut on the ends that make it very easy to get off with a socket too!

Hey,

Which site are you quoting there? Could definitely use that more detailed info to go into the oil sticky thread, the summary page is a little short of detail at the moment....could do with a detailed second post or similar...

Buy a drift one, better than both. i have some weak check stats somewhere comparing particulate size and the drift one came up very well.. i will see if i can find it.

oh and if anyone is in melb and want cheap MOTUL i usually stock about 3-4k of the stuff atany time and will beat any price, especially if your a regular :D i supply the melb s15 club etc..

Hey i just wanna add some advice from experience:

Used a drift filter in my gtr and on startup, the oil light takes 2-3seconds to turn off and for the oil pressure to ramp up.

Changed to coopers filter and it takes less than 1 second to dissapear.

end story, will never use drift products again!!!

    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
    • Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.
    • When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
