Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

10 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

Didn't you buy one of the LN motors? I'd use their recommendation. Good info attached discussing break in oil, but call LN. http://www.enginebuildermag.com/2014/10/break-in-oils-and-assembly-lube-needs/

POST 4Original post

I thought LN used Joe Gibbs Racing's DT40 oil? They also have a break-in oil that is recommended as a flush before switching from Mobil1 to their DT40. Definitely check with the mechanic who did the work. You don't want to void any warranties. https://www.summitracing.com/search/product-line/joe-gibbs-driven-br-break-in-motor-oil

POST 5 / ORIGINAL POSTEROriginal post

I did buy one of L&N engineering's motors . It was on sale so it is not supplied with the oil you have to buy it separately and there are many flavors .And motors on sale only have a 90 day guarantee. 2 year warranty is 5k more. I did call and am playing phone tag with them. Thanks guys

90 day warranty eh... hmm, now that is serious confidence in their rebuilds...

POST 9Original post

When Flat-6 delivered my car after rebuilding my engine it had Joe Gibbs Racing HR in it. I was told to use that for 2,000 miles then change over to DT40. I've used that ever since. But I would follow whatever LN says to use.

Reduction in cost = reduction in warranty. Pay full price if you want the full warranty.
