-   -   ARTICLE: Synthetic oil vs Mineral oil (https://www.team-bhp.com/forum/modifying-car/17917-article-synthetic-oil-vs-mineral-oil-298.html)

It's not recommended. Never flush a Honda engine at least. It will actually damage the interior of the engine.

Our swift VDi is due for its 70K service. Until now, we went with mineral oil i.e castrol MGDO 5W-40. To move into synthetic, should i go with semi-synthetic in this service and fully synthetic in the next? Does this require a flush?

The mandovi SA, once told me that first fill of synthetic wouldn't offer any difference and the difference becomes noticeable from the next service and refill. Is this true?

Just a snake oil story. Nothing like that. If you want flush, do it. If not, just save that money for nice snack and get the synth oil filled without flush. Results will be results in either case.

The Helix Ultra synthetic range of oils is used by Ferrari. So, Shell knows a thing or two about engine oils which IMO are good enough for our run of the mill power plants. :) Incidentally both my cars use Shell oils, one with synthetic (Ultra) and the other semi synthetic (HX7). Couldn't be happier.

You need more feedback use the search function on this thread.

No precautions necessary just drain the old oil completely and refill with synthetic. Just make sure the grade is recommended for your vehicle.

And please, please, please do NOT use engine flush. It is NOT required. No car manufacturer ever recommends using it.

No harm done if the sump is 100 ml short of the full mark. But to be on the safe side just top it up.

Buddy, if this synthetic oil is good enough for a Ferrari or race track spec BMWs why do you believe it's not good enough for your Beat?

That aside if your car needs 5W-30 check out the new Mobil 1 ESP 5W-30.

In my forty five plus years of motoring (since 1969) I have never used or even felt the need to use a flush. I did hear once from a 'guru' the best flush, if you need it, is a cheap oil. A flush is exactly that with possibly some detergents added.

I think a flushing oil is a thinnest grade plus some cleanser. We can just switch to synthetic during an oil change just by ensuring as much of the old oil is drained as possible. All the engine oils are miscible anyway.

+1.

I was a big fan, but then found it just does not give anything other than psychological assurance. When I opened my motorcycle engine, it was pristine. The old owner used only low cost Bajaj mineral oil and it just looked sparkling new. Washed with Diesel and kerosene just to be sure before moving Shell synth, but could not see any improvement other than smoother pickup and long drain intervals. My brother's bike shifted from mineral to synth with no flush and it just gave same output as seen on my bike.

No need to clean the inners unless the draining oil is sticky like goo which happens in old trucks and tractors.

Hi R2D2,

My concern was about the viscosity. I am not sure if a ferrari engine requires same viscosity as my humble bumblebee lol:. Jokes apart, I could not find 5W30 in synthetic (now I have, thanks to you :) ) and was not sure if 5W40 is compatible with my car( for which 5W30 mineral is recommended). Guess I shall go with Mobil1 then

Actually that bit about the oil being good enough for Ferrari or race spec BMWs was in reference to this bit:

But I am glad you're thinking of getting Mobil 1 5W30 ESP. May try it myself when may car goes for the annual checkup later this year. You could use Shell Helix Ultra in 5W40 provided it's one of the grades recommended in your car owners manual

@JMaruru- I switched from mineral to synthetic for Swift VDi at around 38k and the oil used was Mobil Delvac 1 and the difference was noticeable and immediate !! No it wasn't the placebo effect either and ever since I have been on Synthetic and the ODO is @ 62k and she still drives like a charm.

I never used a flush as I didn't believe in it !!

I just read the last few posts, and with experience of multiple vehicles, all lakh + , some close to two lakhs and one above 3 lakhs too, I'd say that avoid flushing engines. If you notice sludge in oil while draining it, have your next change earlier.

From where did you source Mobil Delvac 1?

The Mandovi, where we service always say, if synthetic they will use shell.
So, I need to carry the oil if it has to be from Mobil.

@JMaruru - You can pick the Delvac from here

If you are in West Bangalore you can look this distributor

Hope this helps

This is what you need. Its API-SN rated. http://www.amazon.in/gp/product/B00S...f_rd_i=desktop

Weirdly Shell doesn't sell the 5w-30 Helix Ultra in India even though they have it in their line up abroad.

I'd suggest you buy 1 more botlle and top up to the high mark. In any case you can use the rest at next change too. The SX4 manual says 4.3L oil but only 4L goes in including oil filter and it shows at the high mark when cold.

Where in Pune did you get this oil from?

@abhi3284 - I drive a Swift VDi and always fill 3 ltrs only. It is perfectly fine. As long as the oil stays well above min and below max we are good. Filling 100 ml precisely needs a measuring cup and also will result in 900 ml oil opened for 6 months in a dark place. Storage is an issue and hence would recommend 3 ltr option
