    The wife's been complaining about the oil drips from the Jeep. I explained to her that that is a good indicator that we still have fluid in it. She did not seem impressed. So it's going to be about 95 degrees here today in northern Wisconsin and I'm trying to get the oil lines replaced early in the morning. I'm thinking I should change the oil now since it's all tore apart anyway. Winter is coming as they say. Anybody think I should run a lighter weight oil? 10w40?

    It never goes easy, does it? No shops make lines around here anymore. Ordered 2 new braided lines for the oil. Should be here by Tuesday at the latest. Oh well. I put a receiver on the jeep in the mean time.

    Glad you're getting braided lines, they are generally the best. Maybe run 10w30 in the winter?

    I agree with Glenn, 30w in summer and 10w30 in winter.

    I think there's good reason that single-grade has disappeared from store shelves. There's just no good reason not to run multivis oil today. JMO. The only thing that changes is the degree to which the oil thins out with temperature. Multivis oil is still thick at low temperature, and thin at high temperature, just less so. The multivis oil maintains a more constant viscosity with temperature. Not constant, but changing less.

    What's more concerning - again IMO - is whether the oil is suitable for flat tappet engines. Again, my opinion, most conventional oils are going to be fine for our engines that are already broken in and have the low lift and soft valve springs of factory-equipped engines. Full or partial synthetics are also a possible option, and they have the advantage that their base oils deteriorate less in terms of viscosity than dino oils. I run 15W40 Rotella or Delo year-round in the Jeeps, and 10W30 Valvoline synthetic in the VW (roller rockers).

    If you want to run a thicker oil in the summer, run 20W50 ... widely available. In winter, run 10W30, also widely available, if you worry about cold weather starting.

    If you really want single-grade, run VR1: https://www.summitracing.com/search...toview=SKU&sortby=Default&sortorder=Ascending Notice it's also available in multivis (hmm).

    I'm gonna be lucky if I even get the grass cut today. Sheesh it's hot. Motor swap can wait until Tuesday lol

    I generally use 10w30 for most my stuff unless the fsm states something weird.

    One reason could be to get a Non-Detergent oil - whether that is a good reason depends if you subscribe to that theory for older hi-mile engines.

    Running Castrol 20w50 used to be quite popular around here. Had it in a 258, fine in the summer but when it got truly cold around here the engine definitely turned over slower...I was quite surprised.

    went to NAPA to get my lines. I was surprised they weren't braided. I asked the guy "hey, you said they were going to braided steel, what happened?" he just shrugged his shoulders. :n:

    oh well. I will be home from work at 2, get them installed in time for some fall cruising!

    question, should I Teflon tape the new lines? I don't want any leaks.

    If you do...I stopped using tape years ago and switched to Oatley Great White Pipe Joint Compound.

    Withstands high pressure
    Wider temp range
    For all threaded plastic and metal fittings

    20170927_162527.jpg Not only did he give me not what he said, but the fitting on the line is so large I had to remove the bracket holding the oil canister on to the engine block. And then I found out that it is the wrong size completely and won't even go into the hole.

    Beware of pipe joint compound. Truck body companies use it when they put together hydraulic systems. At work we would have a heck of a time getting hoses off when we had to replace them. Didn't leak though.
