    Sometimes I feel the car is hesitant to move off in first gear.

    I find that unless I rev the engine quite hard while bringing the clutch to biting point, it feels as though the car is not reacting immediately to what should be a smooth move off.

    The car was serviced by Honda in August, no faults noted, and generally, no issues at all with the car. I did a 400 mile round trip over 2 days last week and that went off without a hitch.

    I am wondering if 5w30 oil instead of 0w30 could be an issue? It's been using 5w30 since July 2017, although the prev owner had 0w30 (Honda messed up my request for 0w30 during August service, so it was either 5w30 or reschedule!)

    Mileage is 67K or thereabouts

    Oil won't make that difference, More likely to be the clutch needing to be bled or fresh fluid may help.
    Have you checked that none of the wheels are binding when jacked and spun?

    I've not checked the wheels myself, although Lookers sent me a video from the service where they checked the wheels and joints. They spun all but the offside rear, and none had issues according to them. I can jack the car and check the wheels again if this isn't what you mean.

    I found this guide for clutch fluid change, unfortunately the images are missing, any idea where I can find 8th Generation specific guide images? https://h-tune.co.uk/club/guides/clutch-reservoir-fluid-change.50/

    @Nels I only use regular Shell diesel, and occasionally V-Power once in a while.

    @FUGMASTER yes, all good otherwise

    Is yours the I-DTEC engine? Definitely nothing other than hesitancy on the engine / fuel flow side on mine, as she rolls just fine if in neutral

    Our 'other car', a diesel, runs significantly better on VPN than standard.
    When your tank is nearly empty, try a gallon of VPN. (To flush the standard out) When that's nearly empty, pop a few more in and then see how it runs.

    @FUGMASTER yes, I-DTEC. Was driving again this morning and didn't notice the problem so seems to be an irregular thing

    @Nels will give that a shot, will take a while to clear out my existing fuel, still over half tank left to go

    It may not make a difference, but it's worth a shot.
    Is the 1st gear hesitation when the engine is cold, at operating temperature or both?

    I've noticed it during both, no set pattern that I can ascertain

    After monitoring it for a bit longer, I can't get it to happen again. I'm sure it will lurk around and turn up again when I least expect it!

    When I had a hesitation pulling away in first and had to get the revs up around 1800-2000, and the turbo wasn't spooling up until at least 2500+RPM instead of around 1800rpm.... It was down to filthy EGR valve and air mass sensors. Once those were cleaned out, it transformed the car again.

    Doesn't cost much to do, just some time and some cleaning solutions... perhaps £15-20. Not gonna break the bank even if it's not the problem.

    i sugguest first a cheaper options, try change gearbox fluid, check if clutch doesn't slip.
    also as mentioned, replace clutch fluid (completely bleed the system)
