I'm planning to change the engine oil of my Ford Ecosport 1.0 EcoBoost engine and have some queries. I have decided to make a switch to fully synthetic but Mobil 1 5W30 has AECA A1/B1 approval whereas the manufacturer's recommendation is AECA A5/B5. I quote from the manual :

"Topping up the oil: If you are unable to find an oil that meets the specification defined by WSS-M2C913-C or WSS-M2C948-B (petrol engines only), you must use SAE 5W-30 that meets the specification defined by ACEA A5/B5 certification."

I was wondering if I could still use Mobile 1 since the HTHS range of A1/B1 is 2.6 - 3.5 and A5/B5 is 2.9 - 3.5. The only A5/B5 oil that I could find was HP Neo Synth which has A5/B5 approval but is semi synthetic. Please advise.

913C is a spec that is a5b5 plus extra zinc

Mobil Super 3000 x1 formula FE complies with this spec and is a reasonably good oil

That Oil looks be an older SL rated engine oil. I would prefer using an SM/SN rated oil

The extra zinc (zddp) that's been added as per the Ford specification is for a chain wear test.

These zinc levels are what push the oil down to SL grade.

But it is what Ford requires. I've found decent results from using it for my 1.5 diesel Fiesta (which asks for the same spec). Better than the Ford oem semi synthetic oil at any rate.

Thanks for the prompt response. But is that not a Base 3 oil which is usually considered semi synthetic or blended? If this would have been US/Europe, I'm sure these oil companies wouldn't dare to brand such oils as "Fully Synthetic". As far as my knowledge goes, only base 4 oils are fully synthetic.

I spoke to a dealer and was quoted approximately 500 Rs/Liter for this oil. In comparison, the HP NeoSynth A5/B5 is pretty cheap but then again I am not sure of its contents (zinc). What do you suggest I do? Go with this Mobile Super 3000 or explore more? EcoBoost is a complicated engine with its timing chain bathed in oil, hence I just want to make sure I do a proper homework before taking the plunge.

Semi synthetic is blended with mineral base oils.

Group 3 is a cheaper grade of fully synthetic - hydrocracked oils. Group 4 is poly alpha olefin / pao based and yes, better.

However with Ford engines that extra zinc was put in along with a 5w30 with a viscosity at the thinner end of the grade (updated specs in the USA allow 0w30) for fuel economy and to reduce timing chain wear.

So with an Ecoboost stick to the Mobil I recommended or the OEM oil but change a bit more frequently say at 8500 or 9000 rather than the full 10k kilometers if the engine starts to feel a bit rough especially due to prolonged city driving in heavy traffic.

I'm also in the same boat, but I was looking at the 948B spec which is for Ecoboost, it is based on the C2 ACEA spec and only has oils with 5w20 rating. The only oil i've found in India with C2 certification is Mobil 1 Esp. But still that is 5w30.

I'm worried about the thicker oil causing problems in the long run and I might just stick to the normal Castrol 948b spec oil that Ford puts from the dealership.

EcoBoost is compatible with both 5W20 and 5W30, the manual also has it listed. Last time around, the service center at Ford used Mobil Super 5W20 oil in my car and it probably has been the worst experience till date. The car feels gruff and the smoothness has completely vanished. I later figured out that it was 5w20 ACEA A1/B1 that they used and it could possibly be the reason why the vehicle feels strained.

My car has seen a mixed bag of oils that have been used by Ford. I'm sure the factory fill would be 5W20 and I had no issues using it. When I got the second service done, the service center at Delhi used 5W30 citing that 5W20 is not available and EcoBoost is compatible with 5W30. This time around in Jaipur, they used 5W30 Mobil Super and I immediately noticed roughness in the engine. I'd prefer to stick with 5W30 considering our harsh climate.

This is available on Amazon and might fit the bill - except for the super high Zinc levels the Ford spec requires.

Just one last question. If I prefer to go the fully synthetic way (group 4 base) which one would you recommend amongst the below?

The second is an ACEA C2/C3 - and Ford USA spec allows 0w30 ACEA C2 - so you should be able to try it out.

Give it a try, else just buy the cheap Mobil 3000 I pointed you to, and change every 8000 or so km.

Tried procuring the Mobil Super oil you specified and it's only available in 3.5 liter cans. I will have to end up buying two 3.5 cans and its sheer waste of money. Alternatively spoke to Bhuvan from Amsoil and he suggested the OE series 0w20. I'm super confused now

Yeah. Use the remaining oil for a topup later / your next oil change.

The 0w20 might work - it has the 947a spec and acea a1/b1 for where its super cold,

Ford WSS-M2C948-B
Largely based on the ACEA C2 oil sequence this spec requires a low SAPS 5W20 oil and is primarily designed for the 1.0 liter, 3-cylinder EcoBoost engine. Contains in-house tests for fuel economy and piston deposit control. Oils meeting this spec must provide a 0.9% fuel economy improvement over regular 5W-20 oils.

These come the closest among more reasonably priced oils but caution - the ford spec is extensively customized from this

I guess this is the Honda oem oil that's manufactured under license in India

.

In such a case if you book an appointment prior , they will most likely order the oil in advance. In Ludhiana the dealer told me that they barely get 1-2 ecoboosts a year to service and advised me to book a slot a few days before so as to get the spares easily for service. I have seen using them 5w20 ecoboost oil straight from a 5L can.

Should I go for Mobil 1 5W30 instead of Idemitsu? It has WSS-M2C946-A/WSS-M2C929-A and ACEA A1/B1 approval. I'm getting it for 2800 bucks.
