Oil Change and analysis

[Martin77]

Hi everyone,

A friend of mine drives to and from work which takes approximately 100 km per day. It is all highway driving and he drives gently as he needs to save petrol. He shared with me the other day that servicing for this car is expensive due to the high km he is doing.
Has anyone done this before and know where he could send his used oil for analysis so that he may be able to extend his service interval? Is there any particular chemical analysis (tbn, iron, ...) that must be done?

[EKVTIR-T]

Those kms arent extreme. Just use a high quality synthetic designed for long intervals https://www.nulon.com.au/products/Full_Synthetic_Engine_Oils/Full_Synthetic_5W-30_EURO_Engine_Oil

Also if he is driving so gently to get better mileage,how can he afford to get analysis?

[beeza]

^^ yes.

Cerma stm-3 extends oil changes also.

[Martin77]

Thanks,
I made a mistake its 200 km per day. 100 km each way.
Normal servicing every 125000 for his car is OK but because of the frequency (5 times a year) it can be expensive.
Yes good oil will allow extended service interval but its a good idea to check it (oil analysis) to make sure it is OK.
Redline oil recommend 15,000 to 18,000 miles service interval in highway driving which is equivalent to more than 25,000 km. Thats crazy... I don't think I will do that without checking the condition of the oil. Once checked at maybe 20,000 km then with similar style of driving it should be ok to go on without regular checking.

That is not expensive... I bet his paying for the servicing. If i were him I'd invest that money into tools and he will make his money back within the year.

Also note its not oil these days thats the problem, synthetic oils are pretty good they can do 15k KMS easily.
Its the oil filter that stops filtering oil at around the 12K mark.

Way I see it, oil i'd be using penrite 10w-50 $50 oil filter $15. Thats $65 x 5 = $325.

I'd also add, Gearbox Oil $100, Upper head cleaner $15, Injector cleaner $15, Coolant $55, Oil Flush $15 (do this once a year) - $200

Add another $200 - for things like tyre puncture repair, wheel alignment, ac regas, air filter, fuel filter, spark plugs etc etc (these are not needed every time, good to do one at time when you can or when its needed) Emergency cost.

Total - $725 running cost a year is cheap af (fuel + rubber + rego + insurance not included). No need for top oil if you arent limter bashing clutch kicking.

[Martin77]

You are right. He is paying for servicing. I did encourage him to do it himself, willing to show him and also lend out my tools.
One problem is that he is not mechanically inclined and does not have the confidence to do it.
Talking about filters, the new synthetic oil filters (with wire mesh backing) is designed to last a lot longer for cars with long service interval.
I noticed ryco has now released this new filter called syntec which I used for my brothers corolla. It is made in China though.
The one for the accord is z547st and it cost $30 in supercheap (normally) but can be obtained cheaper in other online store. This is not needed if we change our oil at every10k km.

[beeza]

Why not you do it?

[Martin77]

It did come across my mind to do it at work (after work). It probably will look a little dodgy.
He lives very far away from me.

I am still interested to know whether engine oil (with good synthetic oil filter) can last 25k km (modern car) in highway non spirited driving condition? I'm sure there are a lot of people in this same situation which can save money and time if they don't need to do it every 10k.

[beeza]

You can do 30,000 MILES With cerma oil + cerma treatment. Don't believe me?

It's been proven. Just swap the filter at 12k.Just need to find anAustralian stockist . Shipping is a bit much on ebay.

But hey,don't listen to me.

Stick to the recommended-by-manufacturer limits and oils and you will be fine. Change at the intervals , more often if under severe operating conditions (lots of stop start , excessive heat or dusty conditions etc)

Dont use any additives or super oils just drive the dam thing and it will last

[beeza]

FYI Cerma IS NOT an additive.And by 'super oil',well I don't know what that means.

OP wanted a solution and I gave him one.

Benny,you offered no answers and then shot mine down.Can you see that?

BTW It's not the first time,it's what you tend to do.Now,a little heads up for you - You don't have all the answers mate and sometimes you need to listen and learn.

Who is talking to you ? If I was quoting you , I would of quoted you. I summarised points about what is the correct thing to do as per manufacturer specs. Info on here is cached and will live on the internets searches - its best to give proper specs rather than opinions.

OP - if you are to use additives or other specs of oil beyond the intended for that engine , you cannot warrant the longevity of the engine. This applies to any claim against the manufacturer too.

[beeza]

Yeah yeah whatever,I knew you wouldn't see.

What's a super oil?

Wow 30k miles that's over 50k km. Have you tried this Beeza?
One thing that would be useful is to test it yourself by doing oil analysis maybe every 17k km (take a little oil out from the dipstick) and see if the oil does last 50k km. Then no one will mock Cerma stm-33 supplement.

Thanks for the recommendation Bennjamin, I don't think my friend can afford any oil supplements anyway. He will have to learn to do his own servicing.

[beeza]

STM-3

U won't stop the haters mate,they come in droves and they don't stop coming.

The tests have been done to death with cerma Martin,to death. EVERYBODY is a critic.

If anyone is actually keen to look for themselves go to youtube (it's really hard lol)

[Martin77]

STM-3

EVERYBODY is a critic.



I dont believe that. I am sure everyone (like you) also wants to save money and have their engine to last longer, its a common desire amongst us.
Its just that it is a big claim and people need more evidence. The best evidence is for you to trial it out, get an oil analysis and post in on the forum.
I am sure many people would like to see this analysis. I sure does.

[beeza]

Mate,my energy with trying to show others what I've learned in wearing real thin,let me tell ya.I have no desire what so ever to do that.

The way I conduct myself on the forum has allowed me to be on here for 11 years now.Not many last that long and regularly make posts.

This between myself and benny has been a long time coming buthe knows I love him for everything that he does for the Honda community. I got a lot of respect for him.

[Martin77]

Great job Brett. I encourage you to continue with your perseverance.
We may disagree on a few things but as you said, we have a much more important common goals, which is to help out the Honda community. If we set our heart to do this, this forum will be a great community.
Keep on marching on Brett.

[beeza]

I needed that mate,thanks so much Martin.

I don't fish or look for respect but I do expect to be listened too and not undermined,that really blows my trumpet :)

[Shaddow]

Honestly if they want to save money he would be cheaper learning to do it themselves. There is plenty of hightech oils etc out there to extened the life of the change but nothing saves money like doing it yourself.

The first time is always scary when you do something yourself that you've never done but if they seriously want to save money and that's all this sounds like, they should bite the bullet and learn to do it rather than going for oil analysis etc. Probably sounds harsh but trying to do things cheaply at uni is how I first learnt to work on cars.

[Martin77]

You are right.
With the few hundred dollars he is going to spend for the next service, I will ask him to spend this money to buy some tools and show him how it is done.
I hope his Nissan pathfinder doesn't use crush washer that really crushes and cannot be reused. I know, I know, technically we need to replace our washers but I seemed to get a way with not replacing it.
