starletno1fan Posted November 22, 2005 Share Posted November 22, 2005 mobil 1 fully synthetic 10w/40 Quote Link to post Share on other sites
lobotomy Posted November 22, 2005 Share Posted November 22, 2005 Turbo cars need different oil to N/A cars. Mainly due to the excess heat generated by the turbo. Saying that my bro uses Castrol magnatec 10w/40 in his CA18DET (T28 turbo) although he finds that at high RPM's when going flat out that his oil pressure drops drastically, this is due to the viscosity of the oil at high temps5w-40 instead of 10w-405w offers better cold start and short journey protection as it's thinner than 10w and remember this is when 70+ percent of the engine wear occurs.10w-50 instead of 10w-40 - 15w-50 instead of 15w-4050 offers better protection than 40 when the engine is running hot so if you're doing track days or hard driving you may want to consider this option.A word of warning about 60 gradeModern engines do not need a 60 grade, it's really too thick and, even hot-running engines do not need SAE 60 oil these days. (by â??hotâ?? I mean 120-130C). SAE 60 is heavier than most SAE 90 gear oils. If an oil is too thick, it de-aerates slowly, leading to cavitation in the oil pump, or the bearings being fed slugs of air along with the oil.The thickness of the oil will also have an effect on the cars performance.Synthetic Oils instead of Mineral Oils.It is a fact that Semi and Fully synthetic oils are better for your car, they flow better when cold and give a greater level of protection when the engine is hot.It is a fact, not myth that complex engines such as DOHC, Turbocharged, and Supercharged when driven hard will always have a greater degree of protection from a synthetic oil.A synthetic oil is more robust and will last longer (that's why they cost more) mineral oils need much more frequent oil changes but they are cheaper. Semi-synthetic is to some extent the "middle ground" for pennies more than a good mineral oil.Ester Synthetic Oils against Normal Synthetic OilsThe oils that give true benefits are ester synthetics (pretty hard to come by as they are expensive to make although Silkolene still does). The reasons for their application in motorsport and the aviation sector are clear: They assist the additive pack in a motor oil formulation because they are surface-active (electrostatically attracted to metal surfaces), so they help to reduce wear and friction. They are fluid at very low temperatures and at high temperatures they are very chemically stable and have low volatility (donâ??t evaporate away).They also help to prevent hardening and cracking of oil seals at high temperatures.It should be said that there are three types of synthetic oils on the market and they vary in quality and price the lowest being MC/HC (Molecularly Converted/Hydrocracked) mineral oil, POA's Poly Alpha Olefins and Esters.So, there you have it, some advantages and disadvantages to consider, I'm here to give advice so please feel free to ask, I'll do my best to answer you.As many of you will be aware, I sell the likes of Mobil 1 15w-50 Motorsport, Castrol RS 10w-60 and the Silkolene PRO S and PRO R Ester Range so I have plenty of oils to choose from. At the end of the day, I will tell you truthfully what I think are the best but you must use what you are comfortable with.Thanks to Oilman who seems to be on every forum in the UK providing good oil info!

lobotomy Posted November 22, 2005 Share Posted November 22, 2005 The moral of the story is - Get you ass (well car :angry:) an oil temp and pressure gauge. Quote Link to post Share on other sites

ilghap Posted November 23, 2005 Author Share Posted November 23, 2005 Thanks mate.Got a mail from oilman and he said I should use a good quality 5-40.I thought it would be best to use 10-50 as this will offer better protection when the oil is hot. But I guess I should listen to oilman.anyone agree? Quote Link to post Share on other sites
lobotomy Posted November 23, 2005 Share Posted November 23, 2005 Fully synthetic oils keep there properties at high temps better than semi synth or mineral. Oilman seems to know his shit, I'd listen to him. Quote Link to post Share on other sites
BlackTarw Posted November 23, 2005 Share Posted November 23, 2005 There's a new oil just been released which is supposed to be pretty damn good, it's in the news section of this months Japanese performance car mag if anyone has a copy to hand, apparently it's worth 1 second off your 0-100 time...Used to love Catrol R in my old mini, performance and aromatherapy at the same time, luuurvely!

Robbo Posted December 4, 2005 Share Posted December 4, 2005 i noticed in my GT in all the japanese writing on the inside of the bonnet on the stickers it occasionally had 10w-30.this suggests to me what toyota reccomends for a starlet turbo in japan, so its a good basis on what to put in here.i'm not sure how thin the cold start oil can be without having it leak and get everywhere, personally i wouldnt go under 5w. and top no more then 50.I've just done mine using semi synthetic castrol rs 10w-40 and it seems to be fine so far. not sure what i had in there before as toyota put it in.another note: you only need 2-3ltrs max for the starlet. i completely overestimated and bought 8ltrs but i got quite a bit spare now which will give me more reason to do frequent changes.oil filter you need to use a oil filter removal tool and basically get it on there as much as possible - good luck with it, it's a nightmare. dead easy to get back on though, just align and tighten by hand (tip: dap your finger in oil and rub it around the rim of the filter before putting it on, this gives a better seal to hold it on).

Guest Enzo Posted December 4, 2005 Share Posted December 4, 2005 cool rob,does anyone know anywhere i could obtain one of these oil filter tools for taking it off? Quote Link to post Share on other sites

Guest Enzo Posted December 7, 2005 Share Posted December 7, 2005 tanx for that,rich could you source me the part mate? Quote Link to post Share on other sites

Guest Enzo Posted December 7, 2005 Share Posted December 7, 2005 mmm, i dont even know what they look like,what would you need to know to locate it mate? Quote Link to post Share on other sites
scutch0 Posted December 7, 2005 Share Posted December 7, 2005 all halfords stock them, so theyre dead easy to find, its just that theres a few different designs. i always use a draper oil filter wrench, but i dont know how much space you have in the glanza.Rich.

flux Posted October 14, 2006 Share Posted October 14, 2006 so is 5w30 or 5w40 the one to go for?When i had an MX5 turbo they seemed to all recommend Millars or Mobil-1. Quote Link to post Share on other sites
ecksjay Posted October 14, 2006 Share Posted October 14, 2006 the filter is fun, especially if it isnt an OEM toyota filter, and if it hasnt been off in a while..my mate with the proper tool took 2 hours to get the cunt off, hammering a screwdriver through it wouldnt even work, with the air con still in its an absolute NIGHTMARE of a job. good luck to you!! ;)i used valvoline durabled 10w-40 oil, its what my mate uses in all his cars as well as his stockrod race cars and drag cars, so thats good enough for me!

I no i should have but with me runnin that oil before is this going to damage my turbo, seems to be ok but need some re-assurance. Quote Link to post Share on other sites
lobotomy Posted October 24, 2006 Share Posted October 24, 2006 The semi-synth won't have damaged your turbo -- but could be showing early signs of your turbo seals going (as the oil is getting through when the oil is hot) Quote Link to post Share on other sites
BoostJunkie Posted October 24, 2006 Share Posted October 24, 2006 how much am i lookin at to replace the turbo seals. Quote Link to post Share on other sites
sdutton007 Posted May 12, 2007 Share Posted May 12, 2007 Forgot about this, but here we go: The stuff is called Castrol Edge, it comes in 5w-40 and 10w-60 types, GT-Culture tested it against a semi-synthetic in a 0-100 simulated bench test and it was a second quicker...sounds good!I am going to do an oil change on my EP82 quite soon and want to try this stuff out.... popped to halfords and there is Castrol Edge 5W40 and Castrol Edge Sport 0W40. Whats the diff (the back of the bottles doesnt help)???Or does anyone think that another oil would be better in some way???Also, does anyone know somewhere (online preferably, or in cambridge area) where i can get the oil for a reasonable price instead of £43 for 4 litresCheers Quote Link to post Share on other sites
paul w Posted May 12, 2007 Share Posted May 12, 2007 5w 40 will be too thin.will probably smoke as the oil will pass the rings.10w40 will be more suited. Quote Link to post Share on other sites
