Hello Everybody,

i have bought suzuki Cultus brand new last year, having G10B inside, the problem with it is, that it contains cat and contain adjustable tappets,
I need to look which oil would be better for it, I have heard anything higher than API-SJ will going to harm the tappets due to the absence of zddp, but this is going to burn the cat fast, if i move to api-SM/SN, this is going do wear the tappets fast. so far its 20k on the odo, and i have being pouring SM all this time, but now i have moved to API-SJ 10/40.
any help would be appreciated.

I would stick with the SJ, as long as your engine is not burning oil in a great way, your cat should be okay. I've had cats go 150K miles before the zddp was taken out of the oil, don't think that it's that big a deal. I was going to say that your oil is too thick, but I see it's rather warm where you live, I'll just mind my own business. Mobil 1 has a special "European Blend" oil available here in the USA that specifically does contain zddp, it's 0W-40 rated, but some testing shows it's really closer to 5W-30. If that's available in Karachi you might want to use that.

You have the g10b 16v 4 cylinder. Older grade oils such as SG were used in these engines with cats when they were first designed. It is possible that suzuki has updated metallurgy to tolerate low zddp oils. Follow the manufacturer oil type and grade recommendations for your climate and you should have no problems.

Edit: the latest motor oils have reduced levels of zddp but many feel they are still at effective levels to protect non performance cars with flat tappet valve trains.

regarding metallurgy i have doubts on this, there have being some cases reported by my few friends who work on cars for living, noise from the tappets after several thousand kms (60 to 80)K of their customers. they had told me to stick with the SJ.

A replacement cat is cheaper and simpler than a replacement head and camshaft.

Thanks Woodie, I thought the same, i will get away with the cat once it reaches it life.
you think if 10W40 is fine ? or should i pour 10w30 ? or any other ?
temperature range here is 15min to 38 degree centigrade. mostly warm-hot.
