Oil advice and recommendations here!

Are there any negatives to using it? I've got gallons of it!

No not really,

You will get slightly less mpg, the most important thing is to let the engine warm properly before giving it any real load, to allow the oil to get up to temp.

Sure you've answered this before but 1991 964 3.6 100K

For all year round use for a well maintained engine, 5w-40 Porsche approved synthetic, if you do some track time then consider a 10w-50.

Cheers for that.... If I sold my stock the price of crude would slump!

The Comma stuf is not the best quality by a long way.

I would recommend a decent race 5w-40 if you're competing in the car on a regular basis. Low drag and shear stable.

Hi Chaps,

I've been using your Fuchs Titan 10-40 Semi in my 106 Gti on 77k and a couple of light mods (see profile)

If i was to switch to a full synthetic, would it be safe to do so (any special preparation or can i just sling it in) and what grade would be ok for 2 mile journeys during the week, fast road at the weekend and occasional track days ? I change my oil every 5-6k

Ultimately is the difference between semi and full really going to make a discernable difference or should i stick to what i am on?

Cheers

my other car is:

fiat punto 1.2 16v petrol
year: 2001
mileage: 30000

no mods. temperatures here go as down as -20 degrees (sometimes more).

the servicing guys use selenia oil but i never seen what type. i wanna know which oil is the best so i can tell them to change it when the next service interval comes.

im wondering is 0w-40 full syn oil the right choice for me?
and should i stick with selenia?

Steve,

The Fuchs XTR 10w-40 is great quality semi synthetic, if you wanted to change to a full synthetic then there would be no issues, just a good drain of the old oil, put in the synthetic and away you go. For the 106 I would look at a 5w-40, this will give better cold start protection for those short journys and the quality of the synthetic will give better protection when hot on the occasional track day without shearing down (thinning) which mineral based oils suffer from under hard use.

Hope this helps.

Cheers

Guy.

For the Punto,

with temps dropping that low you could get away with a 10w-40 semi synthetic but ideally a 5w-40/0w-40 full synthetic would be the best option.

Hi
i have a 1989 fiat uno turbo 1.3 MK1 which at this time is standard but will have some mods done raising boost to 1Bar better intercooler i am thinking of using a fully synthetic oil what is the best.
The gearbox is a fiat X19 1984 1500 unit what is the best oil fro the increased load from the uno engine
Thanks
Dave

Dave,

I am a big fan of the Uno Turbo, if you are modding and increacing the boost you can go to full synthetic no problem, I would look at a 5w-40/10w-40 for best results but make sure its a true synthetic and not a hydrocracked mineral oil.

For the gearbox, 75w-90 full synthetic is what you want, if it is dealing with extra load and Uno gearboxes are week any way I would suggest the Silkolene Syn5 75w-90 for this.

Hope this helps.

Cheers

Guy.

Further my post a month or so ago and your reply, my OPC has just serviced my Mk2 GT3 and used Mobil 1 15W150 oil, as I had specified that I wanted a thicker oil given the car's extensive use on track.

Previously it was using 5W50 supplied in Germany.

Presumably 15W50 is less effective at providing protection from start up especially in cold weather. At what point should I ensure that I return to lower viscosity oil?

As an aside, the garage suggested I could use 10W60 Castrol TWS. IIRC this is not a full synthetic and would be far too viscous for such a modern engine. But they said they use it in all 996 Turbo engines. Is this Porsche approved?

(They also said, it is basically the same engine as the GT3. True, same block, but it revs 2,000rpm lower than the GT3, does not use the same lightweight materials for conrods, is turbocharged etc etc. Does not fill one with confidence!).

Many thanks

Steve

PS I think next time I will use the ideal spec. oil you suggested. How do I get in contact?

[opieoilman]

I would not have used any of them.

I would have used a race spec 5w-40 like Silkolene PRO S or Motul 300V.

You're simply wasting power by using a thicker oil unecessarily. And..........stay clear of 10w-60!

Hi Guy,

I've got two cars I'd like some advice on if thats ok.

1. Race prep'd Metro GTi 1.4 singlepoint K series -approx 95Bhp. Only gets used on trackdays -no road use, for about 2 hours at a time once a month. I tend to run it for half an hour or so each week to keep things running smoothly. Currently running on Magnatec, getting changed about every 6-8 tracknights, is this oil ok, and should I change it more often?

2. Mg ZS TD. [ie an L series engined rover 45 ]
2.5 years old, currently done 38000 miles. Expect to do about 30k/year, almost all motorway driving (95%) with engine doing constant ~3000rpm. Rarely does a trip of less than 15 miles, so has plenty of time to get warmed up. Will alo get used to tow the metro once get my act together and get a tow bar fitted. Anticipate getting it chipped and maybe de-catt'ed in the next 6 months (from 115bhp to about 130-140), should this make any difference to which oil I use. Currently I use GTX Diesel stuff in it. I have been told that this is the same as the petrol stuff, if this is the case, then can I run both cars on the same?

Cheers,

Pete

[opieoilman]

Pete,

I would be using something a bit better for these cars.

The Castrol GTX is just a basic mineral multigrade oil. For the Rover I would look at a good quality 5w-40 true synthetic and change every 10k or so.

For the track car I would again be inclined to go for a 5w-40 full synthetic to basically deal with the stress and temps put on the engine under track use, a good quality oil will give you 10 track hours before you need to change it.

Hope this helps.

Cheers

Guy.

[pistol pete]

Thanks Guy.

Can you recommend specific brands? Mail me off-line if thats easier.

Is there any real difference between the petrol and diesel oils (again, I heard there was not with the Castrol, just the colour of the bottle), or could I use the same stuff in both?

Thanks,

Pete

Hi,
I'm currently running Mobil1 0W-40 in a 1.8 MX5. Just clicked over 60,000 miles.

The car does two trips of just over an hour each day. 99% of which is done at 4000rpm. Theres no indication of overheating but the temp gauge is one of the sits in the middle regardles types.

My question is would it be advisable to move to an oil with higher temp protection?

Pete,

Give me a minet and I will drop you a mail.

Some diesel oils have heavy detergents in them to deal with the different by products of the diesel engine, however this tends to only really be for commercial use and engines. For normal passenger vehicles pretty much all oils will do both petrol and diesel, this is represented on the tin by the ACEA specs, ACEA A3 is for petrol and ACEA B3 is for diesel.

Cheers

Munter,

This is fine, no need to change.

The Mobil 1 0w-40 is more than capable of running at around 110deg for long periods.

The grade is also well suited to the use the car gets.

Interesting thread Guy. I have just found it whilst researching wether or not to use slick 50 at my next oil change.

Unfortuantly I have allready bought the oil I was going to use. could you let me know if I should return it to the shop or not. I have bought the Comma synerg full synth 5w40 (only one the local motorfactuers had).

its listed here

www.commaoil.com/

my car is

renault laguna 2
2.0 ltr turbo 170bhp (petrol)
38,000mls
all standard.

I decided to change to full synth following the laguna dci turbo/egr valve horror stories at parkers.co.uk. forums. would this oil do, it is their top spec-ish stuff.


appreceiate your thoughts on this.
