    New Problem after Switching Oils...

    Can tread gauges vary that much?

    I use a cheap plastic vernier caliper with a depth gauge probe, and I measure across the tyre profile in each tread groove, at the circumferential positions corresponding to the 4 lug nuts. I get quite a bit of variation. I think its mostly because there actually is quite a lot of variation in...

    Mixing group 3 and ester oil ? Maxima pro racing

    Originally Posted by Linctex Racing oils typically do not have a lot of detergents to help reduce deposits/sludge/varnish inside the engine..... (very low TBN) Seems like they might go well with an HDEO. It'd provide plenty of base, while the racing oil would up the zinc.

    Detonation, Now only at high RPMs

    I suppose it's possible simply adding restriction would work, but maybe not on an FI engine, which might compensate by trimming the fuel so things stay the same

    Detonation, Now only at high RPMs

    A while ago I improvised something to draw water into the filter housing at high revs, though I had to add restriction to the air filter to get it to work. If you don't do high revs often this might work around your issue. If you do, you might need something mores sophisticated, akin to a...

    Oil qualities influencing your decision to buy

    Availability (otherwise, what's the point?) Viscosity. Nothing lower than 10W30 and in practice 15W40 is a working minimum. Additives (old school Zn levels favoured, so nothing newer than SJ). Brand : I have to have heard of it. That doesn't mean YOU have to have heard of it, so China...

    Originally Posted by Wreckage What do you mean the synthetic M1 is more stable? I guess the whole reason I asked all this was because I am using the 0w 40 M1 in my car which is a full synthetic.

    Cold Start idea after sitting for weeks

    Originally Posted by Chris142 Cranking speeds are often not fast enough for the oil pump to pick up oil in a timely manner. Your better off to start it. It will pump oil immediately. I'm not sure this makes sense. I'd think oil delivery is directly related to revs, but wear is related to...

    Cold Start idea after sitting for weeks

    After sitting 3 months I oiled the valve gear, took the plugs out and turned it over for three 10-second bursts, then squirted some butane in it before starting. I used to do the plugs-out thing after a month but now think its too much hassle. The engine won't start unless the accelerator is...

    Does fuel lubricate upper cylinder/piston rings?

    And then there's 2-strokes, which are clearly impossible. In fact, if Herr Benz came to my venture capital outfit with his prototype IC engine design, I'd probably call security.

    Change oil now or later?

    Part of me says that too, though I suppose if the body shop is in Alaska maybe not. Another part of me says stick with the 15W40 when it comes back, though I suppose if you are in Alaska maybe not. Another part of me says "SIX MONTHS in a body shop?" though I suppose that could be normal in...

    Detonation, Now only at high RPMs

    If you replaced the head fairly recently that should eliminate carbon build up from the list of suspects.

    Burning off fuel dilution?
