Oil Confusion

[acetip]

nobody can fail to notice how many times the question comes up WHAT DO i NEED FOR MY ENGINE.

I BELEAVE ITS TOYOTAS FAULT.

AS SEVERAL OTHER OWNERS IVE HAD OWNED SEVERAL DIFFERENT MAKES OF CARS BUT NON AEE SO VAQUE AS TOYOTA IS.

THERE ARE 2 SEPERATE PAGES IN MY AURIS BOOK AND SOME PARTS COTRODICT EACH OTHER.

ONE PART SAYS YOU MUST USE OW - 20 ( YES TO AID CONSUMPTION AND HELP GET IT NEARER THEIR CLAIMED ECONOMY.

THEN IT SAYS 5w - 30 IS THE BEST FOR FUEL ECONOMY AND GOOD STARTING

WHAT IS MISSING IS A SPECIFICATION NUMBER THAT MOST OTHER MANUFACTORS GIVE SUCH AS 500 OR 505 0R 507 AS USED BY

VW AUDI. BMW LOGELIFE 04,MB22931, O.PEL GM LL-B -025

YES PUT DOWN VISCOSITY GRADE 30,40 ETC, BUT GIVE SPEC NUMBER BEST SUITED FOR TEMPS IN THE UK.

BACK IN 1986 MY JETTA 1.6 TURBO DIESEL (TURBO DIESELS WERE AS RARE AS CHICKEN TEETH)HAND BOOK GAVE A LIST OF OIL

FIRMS IE Shell Castrol Mobil FINA DUCKHAMS ETC AND WHICH OF THEIR OILS WERE SUITABLE FOR VW ENGINES DEPENDING

IF THEY WERE PETROL, TURBO DIESEL, NORMANLY ASPERATED DIESEL (NON TURBO).

I REMEMBER BACK THEN Castrol ALONG WITH A FEW OTHERS DID NOT PRODUCE AN OIL SUITABLE FOR TURBO DIESEL.

IT WAS SIMPLE PICK OUT YOUR ENGINE THEN CHECK WHICH MAKE OF OIL YOU FANCIED JOB DONE WITH NO DOUBTS.

ONLY SYNTHETIC WAS Mobil 1 USED GET A PYREX DISH THROWN IN.

WIFE SENT ME BACK ONCE FOR ME TO GET A PYREX DISH FOR HER MUM ( 4 LTRS £17.00 )

MY LOCAL MR T USES Castrol 5W - 30 THE ME T WHERE I GOT MY AURIS SHOWED ME A CAN OF TOYOTA 5W - 40 AT THE SERVICE COUNTER WHEN I ASKED WHAT THEY USED , ANYWAY THEY BUY IT IN IN BULK SO COULD BE ANYTHING.

I THINK WHAT THEY USE IN THEIR WORKSHOP IS UP TO THEM. NOT LIKE FORD MAINDEALERS THEY MUST USE FORDS SPEC Mobil FE

OR IS IT PE .

TO CONFUSE MATTERS WHERE IS THE WORDS SEMI SYNTHETIC OR FULLY SYNTHETIC USED IN TOYOTA RECOMMENDATIONS.

NOT IN MY HAND BOOK ANYWAY.

WHATS SEMI SYNTHETIC 1% 10% 25% 50% COULD BE ANYTHING.

I wish I could understand what you are trying to ask. :wacko:high

Toyota cannot tell you specifically which oil to use as every user will benefit from slightly different specifications ... are you a high mileage driver, short trip , fast driver, etc etc etc ...

I can see the point of giving general guidance but no more.

Just because VW gave very specific data does not mean the engines ran better.

(See the attached link and read about the VW engines...)

I use a VERY cheap oil in my Auris D-CAT 180.....

latest drains I have used a mineral based STOU API GL-4, API CG-4/SF 10W-30...

It looks very clean after 1000km's

I only pay 30 EUR for 10 Liters instead of the 12 EUR/liter for the Castrol Magnatec 5W-30 A1 or Mobil 1 ESP 5W-30.

what a load of cr*p the engines are designed to run all kinds of conditions and a oil manufacturer designed to cover all conditions and use.

climatic conditions will vary from country to country but the better oils will cover a wider range and car makers

will advise this .

as someone who over hauled disel engines for the last 50 years i dont need someone who engine expereance is to

changing his engine oil and filter coming out with a load of rubbish like this.

imagine toyota owner taking his car in for a annuel service. they say,

yes sir we will give your car its service including an oil and oil filter change,

but we must ask you a couple of questions first, do you drive long distances, do

drive fast, do you drive slowly, do you do a lot of stop start, we must ssk this so we know which of the many oils we have in stock to fill your sump with.

yor talking out of the hole in your silencer.

If you look at service interval schedules there are clear differences between normal usage and severe usage (example taxi drivers...)

The point I am trying to get through ... is that Toyota have provided you with enough information, if based on the information provided you cannot make the decision by yourself, then perhaps you should not be attempting the oil changes...and leave it to experts.

By the way...You overhaul, I help design and develop...so in my "limited" 15 yrs experience, working alongside some of the best engine engineers in the world I probably know more than some assembler/dis-assembler ... and let me tell you something else, you are right...I do not even change oil and filters, as my time is more valuable than to spend time tinkering on an engine...so lets not start being offensive just because people express their opinion...

I realise what you ask for might be nice to have , but it is not necessary.

acetip............Please do not be abusive or discourteous to other forum members!

You asked a question and got a quite detailed answer from one of the forum members with much engineering experience.

Toyota servicing is based on mileage or time with an adjustment applied for "severe" usage.......(That is about in line with most other motor manufacturers)

There is much written about choice of oils and you must read through the specifications quoted in your handbook and decide for yourself which oil suits your driving conditions.

Being abusive will get you nowhere within these forums!

BTW.......It is considered discourteous to type posts on forums in CAPITAL LETTERS..............as this is seen as "Shouting" (which is very rude!)

Any further similar abusive posts will be moderated.

Lots of Manufacturers now recommend different service types depending on vehicle usage.

VW have long life service intervals, Ford now have different standards depending on mileage and type of use.

I am not sure about the new Toyota intervals as regard the new engines but if they specify these new super synthetic oils due to the super efficiency of the new engines would you really want to be putting some of asdas finest smart price oil in?

My personal opinion is modern oils last much longer before they need a change but I have come across too many VWs with clogged throttle bodies and sticky valves to doubt manufactures recommendations.

Put the highest spec in and you will have no worries.

hi aurissem

i may have come over a bit strongr than i should and i am sorry.

but the point i was hoping to get across is that you and i and many others is can undestand toyotas approved oil grades, but time after time the same question is asked WHAT OIL DO I NEED its almost evert week,these owners

must have handbooks to study,if they are asking then its likly ther doing their own oil change, and have done so on other cars they owned but are getting confused with their toyota listing.

i not saying put the oil manufacters Castrol,shell,mobil etc though it would help to add which of their grades

are would help their needs.

hi don21

i sold my mondeo tdci st back in march and its last service (it was still under warranty)in december.

never once was i asked about type of use the car had and as far as i can make out only one oil is used by fords then i cant remember the spec number but it began with M and several numbers behind it.

it was the oil used on petrol and diesl engines,as ive mentioned its made by mobile.

the car was a MK3 so things may be different for the later models (the OILMAN may wish comment on this)

yes vw groupe had a lot of trouble with one groupe of engines and people who own them still have to be carefull

which spec of oil they put in them.

toyota had big problems in the USA with sludge build up in the cylinder heads that drained down and into the sump

blocking the strainer in the sump and starving the oil pump of oil and leading to big end failure.

this happened about 50000 miles.

there was a very a big court cases about this and toyota was forced by the courts out there repair these engines.

but unless the owner could prove they had been serviced correctly show invoices etc toyota did not want to know.

does this sound a bit like owners over here trying to get their oil consumption problems sorted evan though the owner had done the servicing to the book themselves.

but as i mentioned ealier post no where in my handbook is the word SYNTHETIC used.

my car is 2007 model.

someone mentioned buying oil from ASDA, yes i do £32 for 5 ltrs of Mobil esp 5w-30

same oil at Halfords £49.99.

top grade oil at a terrific price,why buy a cheaper oil when you can get a fully

synthetic at much the same price.that meet all conditions of driving.

[varadarajan]

Although the issue of peak oil has gained attention over the last several years (due mainly to oil prices skyrocketing to $147 per barrel in 2008), it's simply amazing that most opponents have no idea what "peak oil" means.

Even more stunning to my readers and I is that no matter how many times we try to explain it, the critics continue to repeat the same argument. No matter what you say or show them, they fall back on this excuse: "The world isn't running out of oil," followed by several denigrating remarks.

The only thing to do is to simply tell them that you agree. The world isn't running out of oil.

If nothing else, my readers know that peak oil doesn't come down to the world running out of oil. So, you can imagine our disappointment when the Saudis announce, "There is plenty of oil in the ground and the world should put aside fears about 'peak oil'."

hi mooly

very interesting reading, thanks.
