Mobil Super 3000 x1 is API SN+ / ACEA A5B5, so the SN+ means it will probably do ok for turbo petrol (TGDI) engines, and A5B5 is ok for BS4 engines that need that spec.

It's probably the same oil Toyota uses as the Idemitsu. You can see the Toyota one is made by Idemitsu itself.

My question was more towards earlier Toyota on older normally aspirated corolla's like mine was suggesting 5w40 Idemitsu as the preferred upgrade oil and now they are back to 5w30.

What would be the difference between these 2 be? 5w30 being less viscous is preferred on older engines or would 5w40 still be a better choice.

I am somehow feeling 5W30 is being pushed to the customers more in the interest of FE and not necessarily as the better oil for the engine. With Bangalore traffic and summers touching 40C, I am wondering is the 5w40 is the ideal oil but just for mileage and some emission maybe, W30 is being pushed more than W40.

Feel free to use 5w40 a3b4 like shell helix ultra, at the expense of a little mileage.

GS Caltex 5w30 is an excellent synthetic oil with API SN and ACEA A5/B5 specs. It is not expensive at all and performs very well. I have been using it in my Swift K Series 2010 for the last 7 years and it runs very well!

You can buy it on Amazon but if you are not able to pm me and I will share the contact details of company folks who will help you source it locally.

CD asked for in the Pajero manual is outdated so you can go all the way to API CK4 - though as mineral is recommended CI4+ should be fine, such as Shell Rimula R4 and that is under 2000 rupees for a 7.5 liter bucket.

You might need to change the transmission and differential oils and likely also the brake oil and coolant, just drain and replace them.

Interesting thread, recently got a Pajero SFX. Changes the oil with a motul 10w30. I have noticed a change in driving characteristic. Before the oil change the car used to leap forward in the first, without giving any acceleration. This has gone down.
Checked with the earlier owner he used to use 5w40. Should I revert to 5w40 synthetic?
Is synthetic oil bad for this engine?

Another query is for my wagon R with a pre K series, F10D engine. It used to be put 20w40. Since I wanted to upgrade I added 5w30 semi synthetic. I've noticed note engine noise and vibration. Please recommend an oil for this vehicle.

The 5W40 shouldn't affect the fuel economy much. Mine is the same Altis as yours and I am regularly using Shell Helix Ultra 5-40 in our type of climate which is hotter and dryer than Bengaluru.

Pajero will do very well on good old shell helix ultra 5w40.

The only motul 10w30 I know of is a jaso ma/ma2 rated oil meaning a bike oil. What was the spec of the motul you poured?

Your old wagonr- try this

Mobil Super XHP 10W-40 Petrol/Diesel/LPG Engine Oil (3.5 L) https://www.amazon.in/dp/B07KMKMQDJ/...K3E5H1W15XPWMH

Due to the lockdown I'm not able to get it in Chennai so I just bought Maximile Feo for my Scorpio's upcoming oil change.

Hello,
I have a 2009 wagon R, F10 d engine done 39000 kms. I had last changed the oil to Wuerth 5w30. It didn't take it too well. The manual states 20w40 or 10w40. Will you recommend 5w30 or 40 considering its age and that i had used synthetic oil earlier?

Also, a 2011 pajero SFX, should I add 5w40 synthetic or stick to 15w40.

Wuerth isn’t all that good an oil. Stick to a good grade of mineral for both cars.

This one should be ok for your Maruti, and at a pinch also ok for your Pajero (because it’s acea a3b3, there’s diesel compatibility as well) Shell Helix HX5 15W-40 API SN Premium Mineral Engine Oil for Diesel & Petrol Cars (3.5 L) https://www.amazon.in/dp/B00QK6R55Q/...ing=UTF8&psc=1

Or get a decent mineral like shell rimula R4 or Mobil delvac MX for the Pajero as usual.

I have an Alto, same year and same Odo reading. I have used Shell HX7 10W40 for many years and found it good, currently using Helix Ultra 5W40.

I have been using Petronas Selenia 5w 40 engine oil in my Fiat Punto MJD for the last 12 years (since we service the car from FASS). Now, I was thinking to give my car to a competent FNG and am a bit confused about the oil.

I was thinking of using the Amsoil diesel oil or the Petronas Syntium diesel oil.

Should I stick on with the Petronas or can I use the Amsoil?

PS- the car has done close to 90k km and is rarely used (about 5k km every year)

Shell Helix Ultra 5w40 will be more than enough and far better than most other oils on the market in the spec of that Petronas.

Thanks for the reply! Will check out Shell Helix Ultra.

One quick question.

I have heard that it's better to stick to a brand of oil if the car has had the same oil always (applicable only for cars with higher odo reading). Is there any fact behind that?

This is the reason why I checked out the Petronas since my car has always been filled with the same brand ever since we bought the car.

[hserus]

If you have filled the same oil since you bought the car and it works for you, stick to it. There isn't any issue with changing brands as long as you stick to an oil that follows the same specification your car manual says to use .. any more than there would be an issue if you filled HP petrol instead of Indian Oil.

Hello Sir,

My K10B Wagonr service is coming up and i was thinking to try Shell Helix Taxi 5W30, though the manual recommends 0W20. I've had a good experience with MGO 0W20(Shell make) and was able to extract some killer fuel efficiency (about 23kmpl) with it, but considering the low running (has only done 12k in 7 years) I was considering switching to cheaper oil.

Also, I would like to know, which oils can be used for Tata Altroz diesel? Manual recommends 0W20 (Castrol GTX, Mobil Super 3000, Petronas Syntium 7000). Is it fine to use 0W20 for New Gen diesel engines with Emission equiptments? I couldn't find a single 5W30 C5 specified oil for now. Is C5 spec calls for 0W20 oils only?

These are the only oils that I could find in C5 spec besides Mobil 1:-

Stick to the manual for any car unless you know what you're doing but any deviation is still a risk.

For the wagonR :
Anecdote : A FNG had replaced the engine oil on my K10B wagonR with 5W30 since he wasn't aware of the 0W20 recommendation for 2014+ cars. I couldn't feel any difference for the 5000km it was in the car. Switched back to 0w20 and didn't note any difference but I didn't pay much attention either. I think the FE has slightly improved with the 0W20 but I haven't checked specifically.

Coming to your reasoning :

- Usage : With that low usage don't you think a thinner oil(0) would be better during cold starts ?
I will assume that the car will be lying idle for days between usage.
The 0W20 makes more sense in this case over the 5W30.

- Cost : I am not sure how cheap is the 5W30 over 0W20. I am guessing a difference of 2-300 for a 3 liter can at best. I got a Castrol Magnatec SS 3l for around 1500. The MGO Ecstar is cheaper and if you're getting it serviced from a ASC they'll charge you for 2.7 liters only which works out to less than 1200.
I doubt you're getting the Shell 5W30 lower than 1100 and hence I doubt if you'll save any significant amount in deviating from the manual.
