Thinner oil for winter?
#1
Any of you lot using different oil iin the winter? 5w-30 / 0w-40 or anything like that? Mine is due an oil change soon so could change thickness then if it's worth it.

It's getting changed soon anyway. It would be no extra work yo use a different grade Tongue haha.

I have done 12k in this car now and it had an oil change about 3k into it so it's over due tbf.

But presumably you'd then change it for thicker oil again next summer... Wink

Well looking into the ratings s 0w-40 is thin in cold weather's and then still normal 40w once up to temperature.

So the question should be 'should I use thinner oil all year round'.. Answer is probably not as there's more chance of leakage. What benefit were you hoping for from thinner oil? More power? More mpg? I very much doubt you'll notice anything at all on an old HDi, they really aren't fussy like some modern engines.

Nahh it isn't thinner over all. Urm
Reading about it now. The 0w means it's thinner than 5w at 0 degrees C.
Which is good for cold start ups as it's flows better in the cold and also doesn't cause as much struggle turning the engine over due to the oil being like syrup.
The 40 rating (without the w) is the thickness once at 100

Using 5w or 0w - 40 only makes a difference when the engine is colder. The 0w being thinner when it's cold so it flows better. Then once up to temp they behave the same Smile

Just read that some where. Learn something technical every day haha Smile

Yeah that's right, so it'll be leaking on your driveway at cold start but make no difference when up to temp.. lol

Honestly, 10/40 really isn't that thick in the cold though, I wouldn't bother but the decisions yours of course. Smile

Yeah, not much point changing... unless you live in an very cold region, if you do, pm a couple of our Swedish or Norwegian comrades and ask their advice/experience Wink

Hdi's are pretty hardy engines, as long as there's a regular oil change Wink

Yeah, use the same oil year round, change it regularly and don't rag it from cold and it'll be fine.

It's a HDi ffs... You can chuck any old shite in and redline them off your driveway every day, still cant break them! It's everything bolted to them that breaks. lol

If you use oil that's too thin it can drain out of the hydraulic lifters over night and then you get a rough start up. The different oils are for people in extreme climates.

I'll be running 5w40 in my Nissan, but it does get 2-4 oil changes a year anyway so it's no biggy.

The engines aren't unreliable, never said they were, still see hone marks on properly high milers with no history! Everything bolted to them is the problem though, including the rusty chassis' lol. Tongue

I have plenty of mechanical sympathy though...had to after owning TU's...go over 1k rpm before it's up to temp and shit the headgasket. lol Cringe if I have to make an overtake before the cars up to temp even now. lol

Just use recommended oil. Trust PSA more than people on a free online forum.
