My Engine has less than 30,000 km so I wouldn't have thought engine noise would be a problem. Anyone else having this issue? Or has anyone else tried the Lucas oils additive products?
Ticks on cold start are kind of common-normal until the oil warms up and flows up 2 the top end. Ifs its going away shortly, I would not worry at all. You can try different oil, synthetic maybe?
What kind of oil filter you using? A cheap oil filter without or non working anti drain back valve will not hold oil on cold starts.
Oh..... Never use oil additives (snake oil)
Oil itself already has additives and adding to them won't make it better.
Scrap the Lucas and get your self some good oil
