Guy, Can you expain Exactly why Magnatec (readily available) is not considered a good oil, as its the only Part synthetic oil, as far as I am aware, that has stated ester content rather than just synthetic which could be just GIII. High Mileage oils do have a different specification <a href="http://home.comcast.net/~dsmphotos/cgtx.jpg"><a href="http://home.comcast.net/~dsmphotos/cgtx.jpg"><a href="http://home.comcast.net/~dsmphotos/cgtx.jpg">http://home.comcast.net/~dsmphotos/cgtx.jpg</a></a></a> <a href="http://home.comcast.net/~dsmphotos/himile.jpg"><a href="http://home.comcast.net/~dsmphotos/himile.jpg"><a href="http://home.comcast.net/~dsmphotos/himile.jpg">http://home.comcast.net/~dsmphotos/himile.jpg</a></a></a>

hi
my 2000 bmw z3 2.8 staight 6 with 55,000 miles, no mods, goes for regular service at the stealers. they sware by magnatec. If theres better oil out there surely they would use. Not wanting to lose the stamp in the book do you think they would mine if you bring your own for them to use?

the zed is used for quick road use, no track days, but the oil has to be able to cope with the cold condtions of northern scotland, as is used all year round.i have noticed recently that it is a bit clatery when cold.
your advice is much appriciated

Si,

I am suprised they are putting Magnatec in your car, the correct recomended grade for the car is a 5w-40/0w-30/0w-40 fully synthetic and also a BMW approved oil is an advantage.

The Magnatec is a semi synthetic and not BMW approved as far as I am aware, but I could be wrong on that one.

You are free to take in your own oil to the garage, at the end of the day it is your car and if the oil is BMW approved there can be no warrenty issues, keeping your service stamp.

Remember each dealer will sign a deal to supply oil, some Mobil, others Castrol etc, they are not going to put in the best oil, because this would cost them more money to buy, meaning they would have to charge more at oil change time to keep their margins up.

You are getting the rattle on start up because the oil is not really the best for your car, not giving the best cold start protection.

For a selection of BMW approved full synthetics, go here www.opieoils.co.uk/lubricants.htm

And have a look at the likes of Motul, Mobil, Silkolene and Fuchs.

Hope this helps.

Cheers

Guy.

Guy,

A few % of esters is no more than an additive and at least 10-30% is required. Part synthetic is a dubious term in these circumstances. Is it possible to add some numbers comparing Magnatec with a good semi and a full "true" synthetic.

What do you make of a VI of 200?

[zeddy3]

thank you for that info
in your opinion, since it's had a service only recently would i be wise to change the oil again or can significant damge to an engine occur in approx 1 year (next service)

I will dig out some figures.

I agree, most only contain this.

Silkolene PRO and Motul 300V have a good slug of around 20% which is why they stand up on paper.

A VI of 200 is achieveable but unfortunately unless it is backed up with good HTHS and NOACK numbers it means nothing. Basically the VI Index does not tell you either how shear stable or how volatile the product is and this is important.

You need a high VI, High HTHS and Low NOACK figure to indicate a great oil.

EG.

Silkolene PRO S 10w-50 (Ester/PAO)

VI 174
HTHS 5.11
Noack 5

I'm sure if you look hard enough you'll find better but at what price and availability?

Cheers

Hi
Id be grateful if you could tell what oils best for my Saab 93
1998 2.0 high pressure turbo model
only recently aquired no mods and with 127000 on the clock
Engine seems fine at the moment dont know what oils have been used but it does have a full dealer service history every 10k or so.

I do about 20k a year vast majority on motorways

Thanks in advance

The recomended grade for your car is a 10w-40 semi synthetic or a 5w-40 full synthetic. If you are doing long hard mileage then a syntetic is the way forward for both cold start protection, mpg and extra protection for the high pressure turbo.

Plenty of good choices around, for a 5w-40 look at the likes of Motul, Silkolene, Fuchs, Mobil and stay away from home brands.

Cheers

Guy,

Not far to look - Redline

Have never doubted Redline, great oils, just far too much money by the time they hit our shores, IMO.

Sorry to ask a sales Q

Do you happen to supply small quantities of oil, your website looks as if it caters for bulk.

I'm trying to find Castrol SLX to use for topping up between services on my 03 honda civic R

The honda dealers in my area only have it on bulk order

would it be possible to mail me through the link on my profile?

cheers

Brian

[opieoilman]

We have it in 1 litre bottles, min order 5x1 litres, just email me for a price list.

[e-mail]

Cheers
Guy

[nighthawk]

Thanks for the mail Guy

I'm only after a small quantity though as it's only for use between services. I'll probably sell the car before it's due it's second service.

Thanks anyway.

New question:

What is the recommended oil for an Audi S4 (2.7 V6 twin Turbo), 6 years old, 90,000 miles?

Apparently they have always put Mobil 1 in it.

The VAG group do everthing by codes, so you will need an oil that meets the VW code which will be listged in your handbook, it will look a little like VW505.00 then it is a case of finding an oil that meets these specs.

Let me know what code you have in your handbook, and I will give you a list of options.

Cheers

Guy.

[Bee_Jay]

What a speedy response, I'll get these and get back to you shortly...

S4 is 501.01 which most oils decent oils would meet i should think. re the BMW Z, Magnatec won't be suitable, nothing in the Magnatec range meets the BMW spec.

[Frik]

Guy,

I noticed you mentioned that the gearbox of a Honda Fireblade was "tricky". What oil would you recommend for a Honda 600 FS Sport (F4i)?

Cheers,

Rich.

Thanks for that, my colleague has not got back to me with the details from the handbook.

I know most oils would meet that, but he is currently using Mobil1 and wants to know if there is something better/more appropriate he should be using.
