Hello all,

Hopefully this thread will save some time and people asking the same questions every day. (Sticky Admins?)

I'm more than happy to give oil recommendations and advice here which will hopefully build up to a useful OIL FAQ in time.

We sell the following brands: Silkolene, Motul, Fuchs, Castrol, Mobil1, Amsoil and coming soon Redline (totalling over 300 different oils) and deliver overnight throughout UK Mainland.

My web is here: http://www.opieoils.co.uk where you will find technical data on most the oils we sell.

We are more than happy to help in giving advice as we subscibe to proprietory databases that give us oil data on all cars back as far as the mid 80's.

We can give you the most suitable grade for any part of your car and can recommend products from our ranges. We even keep data and chemical analysis on some oils that we don't sell!

You can always PM or Email me if you wish to discuss a matter off the forum.

If you have modded your car, affecting BHP and temps or are using it for competition/track days then other factors need to be taken into account and I will have to deal with these enquiries individually.

I will however need the Make, Model, Year, Engine Size, Modifications (stock BHP vs Modded BHP) and stlye of driving (road/track) etc and I can more accurately recommend the correct viscosity for you.

Please also bear in mind that modding your car or using it in "anger" means the need for a more shear stable oil that will "stay in grade" rather than shear down with use so I would always in these situations recommend the use of a proper ester/pao synthetic oil, not a petroleum oil as is commonly sold and labelled as a synthetic oil.

Please feel free to ask.

Hope this helps

Cheers

Guy

Flea, ive got some temp tabs that goto 110deg if you want to stick one on the sump to get an idea....

I guess asking advice on oil that you dont sell is a bad idea?

110 won't be enough round a track I'd guess, suppose it depends on the difference between inside and outside of sump though?

Stuart · Posted: Wed Jul 04, 2007 12:45 pm Post subject:

tbh if the oil goes above 110deg in the sump then you really really have something to worry about lol.

Its only for an idea for the cost of a stamp, rather than a £200 sensor/gauge

I'm starting to worry in that case lol.

Was going to say if you have oil in the sump OVER 110, surely engine temperature oil will be more like 130-140??? twisted

Stu sounds good mate, I got an Auto Gauge oil temp gauge what was in the GSTi but don't fit in with the rest of my car too well (looks to bling).

won't the fact that engine oil pouring continuously into the sump at 140degrees heat it up though? Confused

Stuart · Posted: Wed Jul 04, 2007 6:10 pm Post subject:

the sump is there to cool the oil aswell as have a store of it... so yeah if the sump oil is over 110deg then the oil sat in the engine itself is gonna be V hot indeed.

Out of interest why are nearly all recomendations for a thin oil? granted pumping losses are less but the initial pressure dip and higher change of the oil venting from seals is a bad thing?

Why wouldnt you use for example a 10W60 or 15W50 fully synth... have a rough mind of say enthusiastic road/timid track use + sitting in traffic a bit where temp stability is kinda usefull?
