Best Oil To Run?

[rhodieee]

Hey guys what's the best oil to run on a 25det? Only mods is pretty much spitfire coil packs and fuel reg and high flowed turbo. Did own a Evo and ran Penrite HPR10 fully sythetic, now in the Rb world and don't know what oils the best to use? Thanks!

haha.. did you try doing any research?

there's an awesome thread that will explain it all for you.

or you could just use what you know.

Check the Penrite web site

(turns out HPR10 is also recommended for the R33 GTSt)

Nismo.

Or pay a quarter of the price and run any synthetic 10W-40.

My picks to suit various budgets - it is more important to change every 5000kms / 6mths whichever comes first, more so than a more expensive oil over a longer interval.

Under $30 - Gulf Western Syn-X 3000 10w 40 - solid performing semi-synthetic (refined mineral base) only published figure is the TBN of 9.02 (solid for 10,000km intervals) and good pour and flash points.

Over $40 - from light to heavy 40w oils - Shell Helix Ultra 5w40, Nulon Fast Flow 10W40 and Penrite HPR10 (10w50 extra 10 which is just a strengthened 40 weight) - all use a Group 3 refined mineral base, however they improve on the Gulf Western oil by meeting the synthetic standard of ACEA A3/B3, as well as many euro extended-interval standards such as Mercedes 229, and BMW ll-04.

Over $80 - my pick would be Redline's 10w 40 standard motor oil, which offers IMO the best combo of detergent for street, and high temp/sheer resistance for performance (HTHS of 4.4, compared to the Shell which has a rating of 3.68).

All these oils have a good combo of cleaning detergents / high-temp/sheer performance - IMO the difference in competency isn't alot over a 5,000km/6mth interval of street/spirited driving.

Factor in track time and extended change intervals, and the more you want to consider a higher priced oil like the Nulon, Penrite and Redline.

Penrite 10 tenths racing, Motul 300v or Mobil ultimate allround performance.

Those 3 oils are one of the best out there for turbo charged cars. Viscosity is obviously dependant upon engine mods, driving conditions and weather.

Canola

What brand? Crisco?

[Hadouken]

The $2 special option

I'm at Costco stocking up in bulk

[mr skidz]

Peanut oil goes alright

[rhodieee]

Not to sure what to run.. Stuck between hpr10 and 10 tenths

Do you think your engine will explode if you get that choice wrong?

[admS15]

Agreed these are out and out performance oils, however they are designed to be run on track at high temps with high sheer stability (which is good), and then changed after each event - the result is the detergent package in these hi-performance 'track oriented' oils is usually poor and not ideal for day-in-day-out start/stop accustomed to a street car

the 300V is now specifically a track-oriented oil, with very little detergency for 5,000km/6mth intervals

the Penrite 10 tenths isn't far behind however they should have some street manners - my pick is still the HPR10, but the 10 tenths does have a Group IV PAO basestock, where the HPR10 uses a Group 3 refined mineral base

I did a little research based on what you said and 100% agree. Motul 300v is track oriented.

To the OP, i stand by the Mobil ultimate all round performance as its one of the best oils out there made for high performance cars. Its more expensive (around 100 dollars for 5litres) but its pretty damn good. To put it in perspective, i have been told a few guys have used this oil in their old ferrari's and its never skipped a beat.

HPR is also pretty decent. My mate is running penrite Everyday fully synthetic in his G6E turbo which is pushing 330rwkw.

You shouldnt really go wrong. Ive tried different oils in my evo ranging from castrol edge, motul 300v, penrite hpr, penrite racing, mobil ultimate all round etc.. and by far mobil was the best for daily driving.

You're on the money with Mobil 1, based on many UOAs (used oil analysis) in the US, this has proven to be a very, very competent street/track oil

Although they have changed to a refined mineral base but extremely competent additive pack making the overall product possibly better than the previous Group 4 basestock version

The RRP of $105 is a lot of money though, and i think there are better street oils out there like Redline, Amsoil and select Elf.
