I'd be happier now refilling the gearbox with the specified oil.
Hope u get sorted,say it's down to the ppl you brought it to rather than a dodgy car,
My last 6 cars have been japanese, mostly imports and honesty can't fault them,
As long as service is done ( on time and personally I always change oils early)
I'd keep all paper work,jobs done,time,etc etc,
Get receipts for everything.
If it was me and my car was under warranty I'd change main dealer ASAP
You'd need to be v unlucky to get a lemon 🍋
Persevere but be patient also,
And fairy,most mechanics fiba decent job,
Problem with some main dealers is that work carries out under warranty is pushed back as long as possible
That's my take on it.
PS I only use mechanics with decent reviews,
Yes I love on a small country and it's easier to check up on persons past work etc etc
But with due diligence you'll find a reputable one
Save u a lot over time,as you'll build up a relationship with same.
