Possibly had the oil left in for too long between services at some point as well.

probably could use something like this before your next few oil changes.

it didn't help me much before a 240km sludged up hyundai rebuild,but could help you.
the problem with our cars is this will also be building up in your hydraulic lifters,eventually causing the annoying tick tick tack noise.my na6 has 200k plus kms,was similar looking to yours,but had noisy lifters especially on startup.doing this a few times made it better.autobarn has it on special on nearly every sale they have.

hmm that product sounds alright i should give it a try before next oil change.....

though i thought the nb8b motor didnt have hydraulic lifters and ran standard shim under bucket setup? anyways many mx5's iv heard on cold start have the cam train tap..........

that product is not a lifter noise product. it is a oil sludge/residue remover.

yes NB6/8s have solid lifters.

you should only hear cold lifter noise on NA6/8s.
