Re: Oil Recommendations
 
Hi there oilman,

My first post on this site having been a member on mg-rover.org for a while though.

My question then, I have an 04 (MK1), 120 ZR. Its going in for its 2nd service tomorrow (25k). I want to change the gearbox oil but am unsure as to what it needs. I was under the impression that my car has a PG1 gearbox and MTF 94 is the oil of choice for it, is this correct? I tried an Ex Rover and Honda dealers but they dont stock the stuff. Are there any other gearbox oils i could consider.

Oh, car is used daily, it has a K&N panel filter and b/box.

Cheers in advance.

MTF stands for Manual Transmission Fluid and it is a very thin oil used in some boxes. Surprised the dealer doesn't have it.

I have two on my site Castrol SMX-S and Amsoil Synthetic MTF

Cheers
Simon

Thanks for that Simon.

What grade is the Castrol SMX-S? Left it till the last minute as usual so just trying to get hold of some for tomorrow.

Cheers.

Actually cancel that Simon, just checked on your website, Doh!! Checked with my local Halfrauds and they have some.

Thanks for the help.

You might also want to check out Land Rover and Unipart MTFs.

Can you advise about Castrol TXT Softec Plus 5W-40? Is it fully synthetic or not, and is it suitable for K series 1.6 engine with about 70.000km?

oilman 14-03-2006 14:27

Re: Oil Recommendations
 
It is suitable (and it is labelled synthetic) but is in fact a hydrocracked petroleum oil.

Cheers
Simon

Hi Simon. Can you tell me any thing about " Chevron supreme synthetic, sae 5-40, apl/sl/cf , acea:A3/B3"? If it is any good would it be any good in a standard zs 180? Thanks, Tony.

oilman 16-03-2006 23:10

Re: Oil Recommendations
 
Very cheap if I recall correctly, at costco?

I know little about it other than the fact it's hydrocracked.

Stock road car, should be fine but there's a whole lot better out there.

Cheers
Simon

Simon,
thanks for my recent order from yourself.

Our MG ZR 105 will be 12 months old in May. Only done 2,000 miles, would you recommend 'Mobil 1' on an engine this new?
Regards,
Gaz.

oilman 19-03-2006 13:07

Re: Oil Recommendations
 
Daz,

Yes that should be fine, it only really takes about 1000 miles to run in, in if doubt though use a semi for another 1k.

Cheers

Simon.

Re: Oil Recommendations
 
Hello there,
What is the best choice for my ZT diesel (131 bhp) 2005.
It has done 23.000km's and is used very often for short tracks so the engine stays cold most of the time.
My other car is an MG (of course) :) in fact MGB 1971. I'm now using 15w50 in it. The car is for long summertrips only.
And is 20w50 still a good choice for the gearbox in this classic?
Cheers (with some Old Speckled Hen if available here in Holland) :beerchug

Interesting research on box oil

http://www.quantumechanics.com/categ...index&catid=11

Apart from std 20W50 Millers have a classic mini version which should increase protection and Penrite have have some oils that look suitable re the above.

Synthetic (Royal Purple) may cause a problem with overdrive although the EP additives may be less corrosive in modern gear oils.

Hi there,

Non-MG this one but I wonder if you can help..

My old man's 1993/L Jaguar XJ Sovereign 4.0 (3980cc 6cyl) needs a service and I would like to know what oil I need... Its the XJ40 range, it has 86000 miles on the clock and he only does about 3000 miles a year these days..

Any info would be a great help.

Hi Simon, thanks for the reply. What is your suggestion for the next oil change - do I need to continue with Castrol TXT 5w-40 which is in engine now? What about "downgrading" to some 10w-40 semi-synthetic? When I bought the car before about 6 months it had about 60.000km and was filled with some "unknown" 10w-40 oil. Soon after I replaced it with Castrol TXT. Now I am not so sure is it a really right choice.

Re: Oil Recommendations
 
Hi,
I'm storing a 1969 MG Midget, however have drained gearbox and engine oil and imagine would be better to stand it with oil in it - which should I get, not to run engine, just to sit there!


Non-MG question i'm afraid.

What oil would you recommend both for the gearbox of a 2-stroke 18,000 1982 yamaha RS200 motorbike and what two stoke oil should I use to mix with the fuel? Want one which is readily avaliable and not too expensive as just a commuter bike

Thanks,
Aidan

Re: Oil Recommendations
 
Aidan - Im not expert on the subject, but if the engine is going to be standing a long time you may want to consider:

1. Putting Reddex down the bores (lube)
2. Turn the engine once a week (either on the key without the plugs in or if the engine is out do it manually by cranking it)
3. Squeezing the clutch and brakes - so they don't seeze up.

Bet you could get some advise from MG Owners or Car Club - give them a ring.

MarkB 31-03-2006 07:16

Re: Oil Recommendations
 
Oh, one other thing. I think your right, better to have the oil in it rather than without - corrosion.

Re: Oil Recommendations
 
5w-40 full synthetic as the top option, the cost route is for a 10w-40 semi synthetic changed twice as often.

Cheers

Simon.

andylew0 05-04-2006 21:01

Re: Oil Recommendations
 
do you mean change the 10 40 twice as often :confused:

oilman 05-04-2006 22:00

Re: Oil Recommendations
 
Yes, a mineral based oil will only go abbout half the distance of a true synthetic.

Cheers

Simon.

MarkB 06-04-2006 08:18

Re: Oil Recommendations
 
Hi Oilman,

What offers the most protection - in terms of engine wear cold? and hot?

Magnatec 10/40 semi syth make a BIG thing of its cold start protection. Is a fully Syth as good or better for cold starts ? (75% of engine wear is cold starts apparently)

Im guessing that when hot, the full syth offers the better proection (esp. if racing) but this only represents 25% of wear - according to the TV advert.

Cheers Mark.

Re: Oil Recommendations
 
SAE Findings

a pair of Mercedes-Benz Engineers (Rudolf Thom and Karl Kollman)along with pair of Shell Oil engineers (Wolfgang Warnecke and Mike Frend)wrote an SAE technical paper (No. 951035) on "Extended Oil Drain Intervals: Conservation of Resources, or Reduction of Engine Life?" Among the many interesting results presented in the paper was a graph showing cylinder-wall wear-rate Measurements correlated with cylinder wall temperature. Cylinder wear rates(in micrograms per hour) were monitored as a function of cylinder-wall temperature in a test engine specifically fitted with radionuclide-impregnated cylinder liners. Three test were done so that three different kinds of oils could be used. In one test sequence, a straight 30 weight oil was used; in another, 10W-30 multigrade; and in the third, straight 10 weight oil. (The test engine was a Mercedes-Benz OM 616 2.4-liter, 4cylinder diesel.) In each case, the engine was operated at fixed speed, torque and temperature conditions until constant wear rates were observed. Wear rates were then plotted against cylinder wall temperature.

The graph of cylinder-wall wear rate versus cylinder wall temperature tends to be bathtub-shaped, with wear increasing sharply at each temperature extreme (as you'd expect). But while two of the oils turned in very similar wear performance, one oil stood out as protecting the engine against wear at the extremes of temperature. That oil was plain SAE 30 (Straight-grade 30-weight). At either extreme of temperature, the maximum wear rate with 10W-30 was more than double that of the straight SAE30 oil. (The worst performance was turned in by straight 10-weight.)

Ester based oils such as Redline are straight-grade
http://www.redlineoil.com/products_m...sp?subcatID=15

The "UMA" of Magnatec is an ester added to mineral oil.

Ester based synthetics should therefore provide better cold and hot wear

Think I'd better have some radionuclide liners! cool2

hi simon, im going to order the silkolene pro s 5w40 for my zs180 which is not modified but how much will i need, you only seem to have 5 litre bottles and not 1 litre, dont really want to buy 10 litres

I think you need (at least) about 5.2 litres on a ZS180.

Cheers Mark.
