The debate about oils goes on. In my last (petrol) vehicle I switched to Mobil 1 and was impressed with the product. At my first service I inquired about using the same oil and was told it wasn't suitable for a (my) diesel engine. I have two questions - Is the Mobile 1 synthetic oil suilable for my vehicle? If not, is there a synthetic oil that is sutiable? Thanks.

Whoever told you that was full of bull manure and ill informed which is typical in the Australian automotive industry at the dealer level. Unfortunatly, in Australia we are living in the dark ages of lubrication knowledge, and it is difficult to find the correct information.

Here is some reading for you:

Yes, I do run synthetics and yes, I do use a bypass lube filter and usually go to around 25,000k or twelve months between oil changes and have a lube oil test from Mobil during that period at 12,000k's at a cost of $35.00. I use Mobil Delvac 1. The diff and gearbox use Mobil 1 Synthetic Gear Lube oil. They will only get changed at 250,000k's in the diff and 400,000k's in the gearbox.
For a turbo diesel engine Mobil Delvac 1 SHC. To get the best value and engine life, a bypass lube oil filter is necessary with synthetics. If you do not intend to keep the vehicle past normal mineral oil life, then you will not get the full advantage of a bypass lube oil filter, but will also not get extended servicing intervals.

From the Mobil website:
Mobil Delvac 1 SHC is a fully synthetic high-detergent/dispersant super high performance oil intended for lubrication of heavy duty European diesel engines. Mobil Delvac 1 SHC has outstanding thermal stability and provides excellent protection at both high and low temperatures.

Application
Mobil Delvac 1 SHC is recommended for turbocharged diesel engines. It is designed for use in extremes of climates and severe operating conditions. Mobil Delvac 1 SHC is fully compatible with conventional engine oils, however mixing should be avoided to gain maximum benefit from the Mobil Delvac 1 SHC advanced technology.

Benefits/Advantages
Superior performance in diesel engines that surpasses conventional engine oils
Diesel quality reserve for longer engine life
Wide temperature range protection and long oil drain capability with improved engine fuel economy.

Sean, thank you so much, I thought I only had Truckser, thepublican, Alex and Aliases that appreciated the information.

You can expect to pay around the $197.00 incl GST. Suggest you try and get them down to $180.00 incl GST which is what I pay for a 20 litre drum.

I got some Motul on special recently and will use it at my next oil change (35000KM) on my GU Patrol. I want to sample my old mineral oil to see how the synthetic measures up in future.

I see on the Spec sheet that it is suitable for Diesel.

Question for you, OziExplorer, when Mobil does a sample testing do they give you baseline values so that you can interpret the data from the analysed sample. Do you fully drain you synthetic oil or just drop a cup full and wait for the results before you drain your oil.

Luke I just fill the supplied sample bottle and wait for the results, which is always in the week. The test kits from Mobil are $35

Do you have an e-mail address I can scan the test sheet and send it to you.

Oziexplore,


ljmiller@optushome.com.au


By the way, I am interested in getting a GPS and have seen the discussions between you and Trucker.

You do not appear impressed with the Meridian range. I was interested in the platinum. Have you actually tried it or are you just repeating second hand information? Are you a Trader?

The reason I am interested in the Meridian is for the Temperature and Barometer functions, a bit gimmicky but I’ll be honest and admit that I am boy who loves his toys. Do you recommend the Emap, 72 or Etrex. I do want to have to replace this unit in the near future, unlike a mobile phone, I want it to be a long tem investment

But what put me off is that GME does not stock their products. I think GME sell qualitiy items, so I wonder why they don’t sell Magellan? I’ll call them after this public holiday weekend and find out.

Luke nobody likes the boys toys more than me.
The Meridian are in my opionion an awkward GPS in every way. If you have never used GPS gear extensively, it would not bother you. The interface/menus can only be described as mongrel, the position of some of the switches a nightmare, and the reception quality is not real flash, the shape and size well ho-hum. The only good hand held that Magellan have produced is the new SporTrak range, which are disgustingly overpriced in Australia. However, they are an excellent GPS.

As for the tempreture and barometric functions, you are better off getting one of those watches that have those functions and they are cheaper. I don't know if you realise, few ever use the barometric function after the first week. You have to set it every day to a known and accurate altitude or barometric pressure standard gauge for a known place and then calculate the offset provided you are in a reasonable close distance. GPS alititude works just fine for my needs, and if I do want an accurate altitude, I let the GPS unit average the reading. I use 3D digital mapping and have the National Mapping Agency DEM (Digital Elevation Model) which gives you the altitudes for Australia, and when I match my tracks up to that data, they are either accurate or not that far out. Elevation/altitude is not something I need to be spot on.

GME are only distributers of Garmin, they are not re-sellers. The best priced Garmin re-seller I know in Australia who gives excellent service in Brisbane is Kimball at:
http://www.ja-gps.com.au/index.html

Personally I am not that fussed on the eTrek either due to reception issues and the shape in your pocket. For what I use a GPS for, I like the eMap. The interface is very quick and easy to drive, the screen is excellent, has a motorcycle bracket which is easy to use, fits in your pocket very well, has good reception under adverse conditions, clips easily into the car and suits my needs. I like the 76Map but there is no motorcycle bracket, will not fit in my pocket easily, and the plug fits in the back which is not convenient for connecting the power/data cable and putting it in your pocket.

How do you want to use your GPS will determine the best model for you.
What do you want to do with it.

No, I don't sell anything connected with the above information.

Hi Oziexplorer,

thanks for the heads up with the barometer, looks more pain then its worth. I check out the Emap.

Did you send that email to me with the scan of the oil test sheet?

If you have I have not recieved it yet. Try ljmiller@optusnet.com.au.

Regards

Luke
