Just an example for you to research, Royal Purple Racing grade was assh@led in an independant test on a performance Gm motor by Shell Rotella/Rimula .......Yes the stuff at the end of the shelf in the oil section at supercheap in the Black and Red Bottle.

Just speaking via another forum to a few people who ar ein the oil industry in the U.S, but apparently it seems Australia is the dumping ground for Group 1 mineral oils !!! Apparently our own oil cannot be used to make engine oil, neither can it be used to make asphalt, so what good is it ?(Vaseline and Petrol ???). BP, Mobil, Shell and Caltex are the refiners, so it seems that most Aussie oil is group 1. GRoup 2 seems to be very rare, either imported from overseas, or refined from Middle east oil which can be used for anything. Our group 3 mineral oils which are used in majoirty of our synthetics and blends is imported from Singapore/Asia. As far as i know Shell control this. So it seems to me on paper, Shell/Pennzoil should have the best base stocks to make oil. It seems all the major oil companies are using Group 1 mainly, with a bit of group 3 or so to bring it up to specs. Bit ****e if you ask me.

Talking to an ex pennzoil worker from the U.S on the BITOG forum, he said Pennzoil dont even use Group 1 any more, only group 2 and 3 oils. Then i am like hang on, howcome we have Pennzoil GT Street Machine from the US with a nice flag on it and its a group 1 ! Now even other countries are flogging off the lower grade oils to us. As previosuly stated, any Shell/Pennzoil oil made here in Australia from Singapore oil stocks would be your best bet. Well priced as well.

has anyone heard of selenia oil? used in alfa romeos, its an ittalian oil. a 5w40 selenia star and i think a 10w60 selenia raceing, they have a diesel oil too, are they any good as a full synthetic? would the star or raceing be good in a gen3, anyone know?

[vxcalais_01]

Yes i have heard of them and meant to be good oils. Very expensive. Is it easily found ?
Im my opinion in those grades, i would use the following

5W40- Shell Helix Ultra, or Pennzoil Platinum (Group 3's), Motul Excess 8100 5W40(GRoup 4 PAO) and well priced. Valvoline Synpower 5W40 can be gotten cheap if you shop around. BP Visco 5000 was the best oil on the planet (after a few sentimental favourites) until BP made the marketing move and bought out Castrol and now only stock Castrol stuff grr. Anyways it can be gotten at a good price.

10W60- Offcourse there is Castrol Edge, but i would be more inclined to try Shell Helix Ultra 10W60. Its full group 4 Pao, some stores have it, but can be ordered in 24hrs by most Auto shops. It was made specifically for the Ferrari "Moderna" Challenge, even says so in the specs. Street and Race track oil, top stuff.

So whats your pick, I know you like Holdens, but do you like alfa romeo or !!! FERRARI !!! better. No i am not advertising my preference hehe

Look at that viscosity index, its off the planet !

that is bad or good? High VI is a desirable feature in a consumer multigrade oil.

Its excellent actually. It means despite its difference of 10W60, in its designed states when thick or thin, it does not change, shear to break down any more that it was designed to. Fantastic oil in my opinion. Index is usually higher for 10W30 oils. 15/20W50/60 oils are generally lower. These performance 10W50/60 oils are pretty high, but this one is exceptionally high.

On a different note, picked up a few of those Repco oil on special at Repco. the ROSM 20W50. Its SL/CF and 6 litre bottles, only $15 including repco filter. At then end of the day its Mobil Super 1000 oil. All Repco oils are Mobil Oil, the one that says Repco is slightly cheaper that mobil, and the ROSM is again cheaper, cause no name, but part no, as Mobil. Used in my inlaws VN and VK. I will even get some. For 5000k changes, you cant go wrong. If a Repco filter cost $5, thats $10 for 6 litres of SL rated oil.

[vxcalais_01]

Shell Helix Ultra 10W60- 188. I cannot find any others. Probably best to compare to Mainlube 10W60 and Castrol Edge 10W60, which i cannot find. Penrite Sin 5W60 is 186, and the 10W70 is 176. Mobil 1 5W50 is 184. Redline 15W50 is 162, maybe too different to compare.

[cpbait]

yeh vxcalais_01, not sure how expensive the selenia oils are, and don't know how readily available they are, but the workshop i just moved into its the only oil they use in there, for all there cars out of a gun and 120ltr drums and 1 ltr containers under and around benches/cupboards, which would be better for a gen3, the selenia star 5w40 or the selenia raceing 10w60?

[vxcalais_01]

10W60 you could probably use all year round. It would also be better for you if you like to drive it hard every now and then.

[cpbait]

yeh i do like to drive it hard every now and then, yeh and my cars done nearly 170,000 kays(bout 167,xxx), cool thanks for that vxcalais_01

Judging from the MSDS above, it seems it may have up to 72% (Severely Refined paraffinic synthetic oils). All oils are parrafinic, except for esters, but the severely refined bit leads me to believe this is group 3 hydrocracked mineral. Could be wrong.(This is not a bad thing). The rest is esters(which are fantastic) and the additive package etc. Looks like a fantastic oil, the cars that endorse this stuff is fantastic.

I have just read that PAO GRoup 4 are - Synthesized Paraffinic Mineral Gp1/2/3 - Refined paraffinic.

[cpbait]

yeh, its ment to be changed every 15-20k but we do it obviously every 10 like every other workshop, looks after the motors better, so this is a mineral oil rather than a synthetic oil? and is it better than the castrol edge? as in it will be good for a gen3?

would explain y its a lighter colour and not a thick darker golden honey type colour. and it goes into alfas and fiats(who own ferrari) so i don't think they would be useing poor oil, and wouldn't suprise me if its starting to be used in the ferraris too.

thanks for that had a look, very intersting

[vxcalais_01]

I think Ferrari will stick with Shell purely for the relationship in F1 with oil and fuel supply. Shell have the money, the base oil, the fuel.

On paper yes it does look better than Castrol Edge, Castrol Edge is a group 3 fully, this one has some ester base blended and seems to have a high additive pack, somethings gotta make up the other 28% ! . I was reading a forum about this stuff a while ago, cant remember.

Colour is not really a quage. See the picture i have attached ? Thats what group 3 mineral hydrocracked looks like. Fantastic stuff. Its legally allowed to be called and marketed as Synthetic, it has nearly all the characterisitcs of a PAO synthetic, for less price. Has better seal compatibility etc. Thats how you Selenia 1st looked, then ester was added to it, and its additives.

The darker colour could purely be additives and how its blended. Some add dyes, to make it brown, green, red, and even Purple. Colour seems to add alot to perception. If you look at Valvoline Durablend, its a group 1 and 3(possibly) PAO) blend and it is a light yellow colour, like mountain dew. Smells good as well. Shell and Nulon oils, especially diesel version i have used are dark and smell like crap. Purely due to the fact they have heaps more additives in diesel oil that is not really needed in a petrol car. Then again high additive oils like ULX 110 and PM are full of additives but smell like cordial syrup. Even looks like it.

[cpbait]

nice, yeh it looks and sounds good, had a look at the selenia website last night, yeh i'm going to give it a shot and see what its like next oil change, see what happens, will keep you posted on how it goes and what its like. thanks for your help vxcalais_01

[vxcalais_01]

Good stuff cpbait, i like trying different oils, especially these exotic ones hehe. Goodluck.

[VSIIISU]

I use Fuchs, I switched from Mobil 1 after finding that it was running a bit too thin. Plus Fuchs = German ist gut ^^

[vxcalais_01]

lol, yes Fuchs is a good oil, need a better viscosity sread, and yes is made in McIntyre Road Sunshine, Victoria. I drive past it few times a day. Based on the euro version.

[andyman]

i use valvoline synpower 10w-50 in my alloytec, penrite hpr10 in my parents rav4, and castrol magnatec in my sisters n16 pulsar,

we use a mixture of castrol mobil and caltex at work, mainly from the varying machinery we work on, different brands have manufactures preferred lubricant

[vxcalais_01]

http://www.penrite.com.au/files/4VPC...E%20STOCKS.pdf

Accross brands, it seems many of us could be using recycled oil already. Penrite once again are the only one it seems to be honest about it......go Penrite

[fadz]

i use and recomend olive oil, extra virgin.

[damo1989]

other.........because i dont use oil..........i have "fully sick - ima ********" skills and lost my license so....no car on the road at the moment.....no oil...


but when i staret driving again i will probably go for something along the lines of Penrite or Castrol

[HK-VS]

Castrol is alright for me.

[maxpower QLD]

I did an oil change on my VL today and decided to use Mobil 1 (fully synthetic) instead of the usual penrite and i'm kinda shocked at how much better she runs on Mobil 1 . It starts more easily , runs better and dosn't feel reall sluggish so yeah its made a huge improvement to the old girl

Usual Penrite, can you list the grades of each oil ? Mobil oils tend naturally to be on the thin side of the scale, for example a 10W40 can vary in cst, say from 98-103 at startup and 13-15 at operating. Penrite will usually be at the higher numbers, but Mobil will be at the lower end. Yes it can be noticeable. If your using Mobil 1 5W50 then the 5W will start better as it is thinner than most of Penrites at startup. After this one, Try Penrite Everyday Synthetic 5W50 and make a comparison. I am jumping the gun as i dont know What Mobil u are using.
