ClubCJ - The CJ Lancer Club

So I've been scrolling through the forums seeing everyone's opinions on the best grade oil to use for our CJ lancers and it seems 5w-30/5w-40 seem to be a frequently said choice, I'm thinking of changing up the oil to a higher grade if possible it's a 2016 cvt 2.4, the cars at 22'000km and has only had OEM Mitsubishi engine oil in it, I do plenty full of STOP and start driving throughout the week reaching around 500km+ a week. I'm not fussing about price but I'd like to have my car using the most efficient grade oil for engine preservation and performance (joy rides ).

I wanna see what everyone puts in their lancers and why.

I used to use Shell Oils in my last car, but now with the CJ its what ever the dealer uses. As long as its the right grade and service is done on time it really doesn't make much difference unless you're going to do some serious engine mods.

Just use a good quality 5W30 or 5W40 and you will be sweet.10,000k change intervals with a new oil filter each oil change.I service 30 odd cars a week and the regularly serviced cars with good oil in them have less problems than the cars we only see once a year.

Yeah I was thinking 5w-40 honestly, will a high grade oil filter make any difference to filtration/performance? Also what are some reputable brands for 5w-40 some I've heard are Mobil 1 and penirite apparently

Mobil 1 for the win

My Mitsu: dealer uses Castrol magnatec 15 40. I will be changing to full synthetic next service, an expensive move as my services are all
free and if you change oil, to other then what they use there is no refund on the oil you don't use.

Will be changing to Nulon fully synthetic 10 40 have used it for over 27 years with 10 out of 10 results.When your on a good thing stick to it.
Rang Nulon and they suggested 5 30 or 5 20. Too thin for me only possible advantage, improved economy. Which is of no interest to me.
and could be a warranty issue.

I prefer the better cushioning of the slightly heavier oil and difference in flow rate at start up from cold with Melbourne weather will not be a problem.

My car don't get stressed much so I just wait for repco combo deal. Last 2 changes were castrol magnetec 10w30 and penrite everyday 10w40. Both were around $27 for oil and filter.

Hmmm, yeah like DURING the week it's mainly Stop and start with slow traffic conditions but other then that I wouldn't mind the benefit from higher grade oil for track/prolonging components

I've seen a lot of 5w40 which would seem to be thicker right? On super cheap auto guidelines they recommend a lot of 5w-40 but also few 10w40. As long as the engine is provided by the protection and even if SO performance benefit I'd be happy, economy would be a nice positive too

I use Penrite full synthetic 10W40, changed every 3k - 5k kms

Hahah yeh kinda is, but it works out to be 3 or 4 track days worth with some daily driving inbetween, so would rather keep it fresh then be sorry

I would have had to change mine twice last year when I went interstate for a few weeks!

haha, mines already been changed twice this year, doing third after this weekend

Suggest full synthetic. 10-40 will keep warranty happy. Change every 10000ks should be OK. Check the oil and depending on how much of your driving is stop start maybe every 5000ks. With the ks you cover this will keep your changes to less then 6 months apart.

Thanks fam! Yeah I was thinking about changing it soon, it's already getting decently brown. I totally forgot different oil would void warranty, they don't supply another choice don't they?
