RE:Best Oil for Evo 6?

I've always used Castrol RS, but thought I'd try Magnatec after reading that someone ( Co-Ord/Ralliart I think) reccommend it.

I've never had a persistent rattle from tappets before, but it started as soon as I fitted the Magnatec !

I'll be changing back to RS as soon as I can get some !!

For what its worth, I'd suggest NOT using Magnatec

RE:Best Oil for Evo 6?

Troy,
From a cold start when the fuel mixture is much richer , the fuel droplets in the air condense on the cylinder walls inside the engine. This will then combine with the oil and pass into sump before normal operating temp is reached. Turbo motors obviously have a higher combustion pressure , which causes the condensed droplets to be pushed past the ring to cylinder seal in greater quantity.
Engine oil chemistry is formulated to cope with this problem to a finite degree and some are better than others , however , if the car is habitually used on short journies the oil will become excessively diluted which will seriously reduce it's ability to protect the engine , this will result in severe wear.
As an extreme example , I know of a car, NOT an Evo , where an explosion occured due to the amount of fuel in the sump !!
Used on normal journies , the fuel does not accumulate as it evaporates at normal operating temp.
By the way droogs, if u are concerned with the survival of yr oil , u can have it anylised for evidence of the above problem and also impending mechanical doom by presence of certain metal deposits by sending a sample to labs specialising in the service, I'll find some details and post asap.

This week I shall mostly be using Redline oil !

Evoboy

Turbo motors have higher combustion pressure than n/a cars - OK

But during warmup???

Surely nobody here uses much (if any) boost before the engine has attained something approaching correct temperature? This being the case, then according to your theory I'd reckon that turbo motors should actually suffer <i>less</i> from this oil dilution problem than many cars due to the lower compression ratio, no?

I'd be happy to stand corrected if this isn't the case.

RE:Best Oil for Evo 6?

Chunky,
U don't have to be using full boost or anything like it , point is fuel dilution is fact , it happens to any 4 stroke engine but on turbo's when any manifold pressure is present it will be worse that an atmo motor.
I warm up my pride and joy carefully but I cannot drive my car without the boost guage moving even from cold start , unless I make like a milk float uphill ,so thats life. Remember though , it's only a problem with short journey use. I had a female friend with a nice Fiesta or Nova type thing , and despite my advise she used the car for work , the distance was 2.2 miles !!!
and only pottered around at weekends , with the oil filler cap removed u wud swear it was the petrol tank not the engine !! If u have no choice but to use a car like this then change the oil every month.
Short journey use is the most arduous a car can be subjected too and apart from oil there are many other problems caused , eg sludging , corrosion etc.
So start up ,don't idle for more than say 20 secs, warm carefully and fully and enjoy.

Bi dudes

It might have changed from 13 years ago.

Best thread revival ever.

Titan race oil is recommended on here a lot.

Depends on what you use the car for and what power.

I run 10w50 or 15w50....track use.

Do a search mate,been done loads of times.

Opie oils for the oil
