It's been a while.
Update;
Car has been running wonderfully. Getting gas mileage of 13-14kmpl without ac in city and 11-12kmpl with ac in city. Long averages out very easily to 15-17kmpl if I am veryyy consistent with the accelerator.
Cultus sounds great, pep and pick up have improved, running on optimum temp. With caltex coolant. I am yet to check the spark plugs, last they were checked was posted here.
Now, oil change is a little close. I have been using 10w30, now I was wondering if I should go down to 5w30? My only cause for concern is cold starts. Right now with 10w30, cold starts are kinda rough, but smooth out very nicely as the car gets up to temp. I know 5w30 should help with cold starts but I'm wondering if 5w is too thin and I'll hear the ticking of the tappets until the car warms up?
What do you guys think? 5w30 or stick with 10w30? I want to go fully synthetic, so company recommendations please.
P;S gear oil needs to be changed, please recommend gear oil too (75w80 is what ill be putting in)
