Valvoline Synpower 5W-40 in TD5

**RRV80** · 5th December 2007, 10:50 PM

yes i posted without doing the correct reaserch before hand, i well know putting the wrong oil in desiels can casue a fair bit of trouble, take for example the new rodeo and navara/pathfinder deisels if the wrong oil is put in it affect injection timing and if the wrong oil is used for extended periods can casue injector and injection pump failures on late common rail engines. Holden has recently rejected many warranty claims on new rodeos customers had servcie at (no names - smaller shops), Nissan navara's are the same dont use the right oil and theyre known to casue problems, as said just becasue rating are the same doesnt mean alot, as long as it meets an industry standard within limits in fine for a consumer. All these are fine and well in anew engine, that has been serviced using the correct oil since new, i also think there is going to be a few TD5's going around with over 200ticks on them and i dont think they are going to be within the same tolerances as they were when new.

You can go put a 5w in a rattly old patrol which most have over 200now many reaching 450ticks, it'll be fine in the short term, but when you have ridiculous amounts of compression in a desiel and you have ****weak thin oil in it, every time the compression ignites the fuel it pound the cylinder into the side of the block, the oil will just be squeezed out of where it supposed to be protecting and be effectivly useless.

But then again, the customer is ALWAYS right.

how many times do I have to say this...

5w-40 ISN'T THINNER THAN 15W-40

re-read the charts and numbers I posted above.

IT'S THE SAME VISCOSITY AT OPERATING TEMPS.

half the time it's the same viscosity at near zero celsius, too.

BTW, something like Mobil Delvac 1 5w-40 has an HTHS number and film strength higher than any mineral or semi-synth 15w-40 heavy duty diesel oil you'd care to name.

Put the PM Lubricants oil in the D2 TD5 today. My first ever oil change so I am feeling very manly! Also have a cut and bruise above right eyebrow from when the drain bolt came out and hot oil covered my hand causing me to head butt the diff. Felt like a bit of a goose but don't they say that cuts and bruises build character!
Anyway. Immediately felt smoother and felt like it jumped away at the lights as well so accelaration seems to be improved. So far I am pretty impressed. Will see how the fuel consumption goes and if it is improved.

hi Rick,

A little OT, I need input from an oil guru.

I have had a customer who regularly changed his Td5 Defender oil, (every 10k) and used Mobil1 5w30. He is an engineer, and knows the importance of oils etc and stuck to the recommended grade etc. He is also the ONLY owner of the vehicle.

We were both horrified to see the hardface missing off 4 of the 5 injector lobes on his cam, and scoring etc on the valve lobes. The vehicle had travelled only 120k.

I have since wondered why this happened, as I have seen numerous early Td5's since with what I would call excessive lobe wear.

Poor hardening? ALL the cams had a 1999 date stamp BTW, even the one I observed in a 2001 model.

Any thoughts Rick?

Anyone used/heard about the Synpower? Comes at $55 a 5l pack, Pilbara Pricing which seems pretty good for up here.

BradM

Can someone remind me of the temperature at which xW viscosity is dtermined?

Secondly, once that is advised, how often does the Pilbara get down to thse temps & below?

Oops! I see that rick130 has already answered my question.

Thanks Rick

Could it have anything to do with Mobil 1 having only API CF spec? Its rather old spec for a modern high-tech diesel engine.

Hi Graeme,

mmm,I would've thought Mobil 1's properties would be more than adequate , and this oil was recommended to him and used by the dealership

I actually asked him had he been using 20w50 K mart oil and got a very ptiful look

Mobil don't recommend Mobil 1 5w30 for a Td5. They say either Delvac 1 or Mobil 1 0w40.

Also I refer my earlier post:

Land Rover Discovery Series II Owners Manual 2003MY

Publication Part No. LRL0545AUS - 2nd Edition
© Land Rover 2003

Engine oil - Diesel engines
Use a 5W/30, 5W/40, 5W/50 or 10W/40 oil meeting specification ACEA: A1 and B1, and having a
viscosity band recommended for the temperature range of your locality.

Engine oil temperature ranges
5W/30 will protect from -30ºC to 35ºC.
5W/40 will protect from -30ºC to 50ºC.
5W/50 will protect from -30ºC to 50ºC.
10W/30 will protect from -10ºC to 30ºC.
10W/40 will protect from -10ºC to 50ºC.
10W/50 will protect from -10ºC to 50ºC.
10W/60 will protect from -10ºC to 50ºC.

Maybe a 5w30 is inappropriate for Australian weather conditions?
