Couple of questions, please?

Google is not my friend, today.
Just had plugs replaced.
When we bought out '99 Oddy, about 8 year ago, I put NGKFR5F plugs in because they was long life.
In between my health took a massive dive and I've let a few things slip.
I put plugs in, close to 100K Km's and replaced at about 205K, so been in a while.
Place I went to replaced with NGK ZFR5F-11.
First question, how long should these stay in?

At our last last service, about 3 month ago I had Caltex Havoline 5W40 put in.
Second question, how long before next service?
Thanks,
Ian.

Plugs are 20,000 - 40,000km range.
Oil change 10,000km or 6 month if it was me.

Thanks.
I thought 6 months was the old days?
I thought Synthetic lasted longer, or is that a fable?

Good service times , and more so as the motors are running at higher horse power than the older cars.

That were a while ago, Jan 15, 2012,
How you find that?
I no remember it?

It was just backing up my 10,000km / 6 months, I see most on that thread agree.

My dad an old school mechanic, always said and still says 10,000km / 6 months. I religiously have my car serviced every 6 months as I struggle to do 10,000km in that time. My brother (also a mechanic) and not as old school says the same.

1. 30 000kms
2. 10 000kms or 6 months which ever comes first. However, I don't see any harm if you do the oil change after 12 months as long as you are still within the 10 000km range.

5w-40 oil is probably on the thin side for your car. It's perfectly fine, but I'd use 10w-40 semi synthetic.

Many years ago I met Sybil Lupp, Jaguar expert and racer and also owner of a Bentley R-Type. Talking about maintenance she gave me good advice: always do all the lubrication jobs twice as often as it says in the manual!
That could be one reason why my Triumph 2000's engine required only "rings and bearings" a few years ago - at 199000 miles.
Needless to say our modern (well, 1999) Honda also gets its engine and transmission oils changed at half the specified times or mileages.

if doing the miles, before summer and before winter ,is old school
