Finding Correct Engine Oil

[Chooti Putha]

For seasoning engines i find the Lanka Super oil 10w-40 is the best after engine rebuilds...I run 200km change the oil & the filter, Then i run another 800km change the oil & filter. Then i use Castrol Edge sport 10w- 60 for races since the higher viscosity it helps me not break my engine

But one thing i have noticed is the Lanka Super Oil cannot be used for a longer period. But it serves my purpose since i need a cheap oil to put in & run my engine in after rebuilds........

'Chooti Putha',

Please do not misunderstand. I request you to inform other member also for their information.

Lanka super oil the reason you say, Lanka super oil cannot be used for long time. I have used in my previously owned Vehicles engines the said oil for 5000KMs or more without any problem.

Dear Sylvi

For my requirement i find that lanka super is sufficient since i use it for maximum 1000km's But it defers with the requirement of others. The lanka super oil changes the color & viscosity even at 1000kms im sure u can run 5000kms or more like u have claimed. But its better to be safe than sorry. Even people who use semi synthetic oils change at around 4500km....

Nilantha, did you verify if it was burning oil or oil was disappearing due to another issue. Both oils are the same viscosity at running temperature so I'm not sure what's going on!

i checked everywhere. there is no leak. i replace all oil seal with genuine parts. but how come no issue with DS40. this happen only with malti grade oils.

Dear,Chooti Putha,

Thank you for your prompt reply post. before improved oils came into the market I use to change every 1000 miles that was from late 1950 till 1980. When it came to Japanese vehicles too I was changing at 1500 KMs.

At present I change at 2500 KMs in my Indian maruti omni.

I have never tried synthetic oil although my friends say they use same in their vehicles and do up to 7500KMs.

Best regards,

Sylvi Wijesinghe.

Is your car Indian, 2008 Jap need 0-30,5-30,10-30 oil, check your manual

ya its a jap one. i cant understand a thing in the manual because its all Japanese.and yeah agents used 10W-30. but the place i serviced earlier used 20W-50.thats why i wanted to know if its ok that they used that one.

Members,

Today there are thousands of motorists who do not know the proper use of aftermarket services.

Not only that after 1977 motor vehicle imports were booming due to starved market we had for 17 years, and every person had money started to import vehicles. Without having proper after market services. It took almost 15 years after that professional auto detailing to come to our country.

We had only unqualified mechanics who became mechanics working in garages who was in business for long time with carburetor engines. They did not possess any knowledge of modern electronics of motor vehicles.

I had a long chat yesterday with a reputed work shop owner he informed me, that he had come across hundreds of ECUs, handled by unqualified electronic technologists to handle ECUs, without proper instruments, therefore he too cannot put them in order, due to total miss handling by trying to change the settings, with various electronic instruments which are not manufactured to do automobile ECUs, and without knowing the correct technology of a ECU designed for each vehicle, Most of them are TV repairers

Even this topic starter opened this thread because he did not know what to change oil in his car one member says the instructions are with Japanese.

Therefore I appeal to the moderator for having started this pioneer automobile forum, to appoint a reputed automobile engineer or few of them who are willing to give free advice on engine transmission suspension auto electronics and aftermarket services what ever the members come across as problems to them on automobiles.

It will be a great service to our motoring community if this free service is started by this forum.

Since you got the overhaul by Edirisinghe, hope you got a warranty on the job. Best to put the issue back to them rather than you trying to find a way around it, since its their responsibility.

Members,

Today there are thousands of motorists who do not know the proper use of aftermarket services. This is true and this is how its going to be, people buy a car just like a TV or washing machine. They just plug and use it but dont bother to understanding the workings of it. This is why auto manufacturers are coming up with stuff like MF Battaries and cars that actually remind the driver when to do a service. This is increasing in SL as there are much more lady drivers than before, including my wife, they just need the car to go from a to b , and thats it. Some of the other people just buy the car as a show piece.

We had only unqualified mechanics who became mechanics working in garages who was in business for long time with carburetor engines. They did not possess any knowledge of modern electronics of motor vehicles. - You are right again, except for mecanics working for the agents most other bass type guys are just not keeping up with the change in technology.

I think the AA is doing something on the lines as what you have mentioned, but its not very easy to diagnose a mechanical problem by sitting in front of a computer , so this may not work. But at least there is some advise which is helpful for most people....

Edirisinghe brothers gave me only six months warranty. i am planing to meet them this month. i did engine repair last May

First of all I'm sorry for bringing up an old thread.

I recently found out that in SL theres a trend of increasing the engine oil viscosity as the engine gets older

For example if the manufacturer recommended engine oil viscosity is 10W-30, it's increased to 10W-40 when the engine gets older .

Is there a proper logic behind this?

I do know higher viscosity oils are thicker so take longer time to rotate around the engine but giver a better lubrication by filling the gaps in between the moving parts well. Where as a lower viscosity oil is thinner and rotates faster around the engine

[chan5]

Modern engines have perfection in construction compared to the engine we had past.there are minimal gaps between moving parts. So manufacturers usually trending to use less viscous fluid. Which can seep through the minor spaces where thick oil can't.

There's no necessity to use high viscocity oils unless your engine is burning significant amount of oil in-between services.

I usually stay very firm with service guys and do not allow them to pour any crap they have.specially with the viscocity.

So the bottom line is.

If your car doesn't burn oil at current grade.don't shift to higher viscocity.
