Can anyone tell me why the handbook says that 10W30 is fine, only if your using the genuine Isuzu Besco engine oil?

The same applies to the gearbox oil being 5W30 if using Besco, otherwise a 15W40 oil is specified.

That seems to be a big jump in SAE rating from genuine to non genuine oil?

Has anyone running a 15W40 noticed any drop in fuel efficiency?

Cheers,

Mimmo

How do you get around warranty with Synthetic oil?

If the motor blows up (odds are pretty good that it wont), isuzu will have to prove it was the oil at fault. There wont be any dramas full stop.

Look at cSt numbers and you will see that some xw30 and xw40 can be similar.

Interested in your comment about using full synthetic gearbox oil, you said "awesome" how much more awesome can it be than normally changing with the oil that was in it.
Can you qualify what "awesome " means? unless it takes away the gear chatter at very low revs I can't see how it can be significantly improved over a perfectly good new gearbox.

IF you had oil trouble,
I like your faith in the comment, "Isuzu will have to prove the oil was at fault"

In no way is that true, Isuzu can refuse to provide warranty purely because you didn't use their Besco oil and DO NOT have to prove a thing.
It will be up to you to prove the oil was of sufficient performance. Can you do that.

Unless you are very tech savvy with modern engines and have an intimate knowledge of lubrication and engine processes, you won't be able to argue against the company, so saying no dramas, is fairly optimistic and a tad naive.
Having represented a friend after an engine failure with a Mazda product, you might find it is neither straightforward or simple.

Who are Amsoil, it's not commonly known here in Vic and can't say I know anyone who uses it. Maybe very good and I don't think you will have any trouble, it is just you can't take anything for granted.

just feels smoother/less vibration through the shifter, and more consistent (less thinning out/more stable?) over longer drives

UOA might!

FWIW the local dealer doesn't use genuine fluids and isn't interested in supplying them either, which is what led me to look for a proper manual transmission 5w30 oil (probably GL2-3?) instead of using engine oil.

if the motor grenades, i'm confident that it won't be because of using this engine oil.

Perhaps since Isuzu has stretched out its service intervals for normal use to 12 months/ 20k, the latest 4jj1 isn't too hard on oil anyway? More likely just a customer grab :)

At the end of the day, I prefer synthetics where others might see them as a waste of money. I've used them in most of my vehicles and believe they are better.

I also didn't find any WA dealerships using Besco fluids for services, can you even buy Besco in Aus??. The ones I spoke to used either Castrol, Caltex, Mobil or Total, and having liked the performance of Total in my previous vehicle decided to find a blend that exceeded the specs of the Besco product for the DMax (I provide all fluids and filters when having services done).

Generally I would have thought a lack of correct weight engine oil or faulty components would make an engine go "Bang", whereas the brand/specifications would lead to premature wear which will really only surface well outside of a warranty period anyway.

My local Isuzu dealer uses Valvoline oils so add that on the list.

A properly spec'd oil will do the job and some are better than others.
The major issue is when you go for your 10,000km or 20,000km, or the 30,000km service and beyond, and the dealer doesn't actually change the diff's.gearbox, transfer case or grease it at all.

Having investigated to prove a point, I have found some with none of the above completed after 20.000km. They should have been changed twice in that time frame. Of the random ones I looked at none had been done after 10,000km
Only a few looked at and 100% strike rate when randomly selected in the street.

Engine oil? everyone is aware of that issue so it generally isn't a problem.

But how long does your running gear last? yes it will make it through the warranty period but how long after, if it hasn't been regularly serviced.
Oil deterioration and critical mass of particles in gears can suddenly cause an effect you don't want. If out of warranty you pay when you should be enjoying the vehicle not repairing it.

All makes and all dealers are worth doing checks on and this isn't just a one brand issue. It is a problem though if it is your brand.

How are you able to test and prove if a dealership hasn't changed your oil? Is there a sample testing place you can send an oil sample to that is affordable and realistic?

I have had an oil analysis done by this mob in the past and was very happy with the service:

I know others that have used them too and have also been happy.
