Experience with oil leak stop additives?

    Had the car in for a timing belt change and service recently, and while they were at it, asked for a thorough check to see where a small oil leak is coming from.

    It was diagnosed as more of a "weep" than a leak, not really news to me as the oil level had only dropped a negligable amount in 8 months (still check regularly in case of it suddenly springing a leak).

    The advice was to use one of those "stop leak" additives. Anyone any experience with these?

    I would like to get it sorted, as I don't like seeing the grubbiness around the engine block and tray underneath, and I'd be concerned about it overnight getting worse.

    What oil is in there now? What car? What year? How much is it losing?

    For older cars it's generally better to use a thicker oil than some additive but it depends.

    Thanks, wasn't sure about just sticking something into the oil alright...

    5w30 is what's there at the minute. The oil on the dipstick is still pretty clear about a month after the service (was the same last time after I bought the car, old oil was more brown and murky before the service though).

    2005 Renault Laguna 1.6 Petrol. As I said, negligible oil loss - I'd estimate 4 mm (less than half a cm) in 8 months.

    Car is in good nick and running well, suits us perfectly and looks nice. Got hold of the previous service history ringing up garages in it's previous hunting grounds and it seems to genuinely have been looked after. So I'd like to get it in perfect nick seeing as I've other priorities right now rather than a newer car!

    Id be happy enough putting in 10w40. But just good oil. Castrol is my choice.

    stop leaks create more trouble than fix

    Aye, I'd switch to 10/40 too but tbh, with that small loss I'd just keep driving and filling up every 6 months. Plenty many cars lose or burn more than that.
