Well the, 'red-line', product is a, Engine 'break' in oil additive.
Meant to be added to, any oil, for break in, at the rate of about 2 oz per quart.
In this engine, the recommended rate is, (for everyday use)
1/8 - 1/4 oz to a quart, of Rotella.
(Most probably more, if another oil, which has no Zinc in it, "ZDDP")
So, if, worried about 'special' break in oil. Just add 2 oz to the first, 2-3 oil changes, then drop back down to 1/2 oz for then next couple. then after 1,000 miles or so, down to 1/8-1/4 oz.
In small engines, I always added a cap full, of some, 'snake oil additive', to the oil. But I truly believe, the long life, is due to the frequent oil changes.
As to cost, let's see, 16oz RedLine, 16.00 +/-.
So that 1.00 a oz, or about, (with recommendations),
about .30 - .40 Cents extra per oil change.
Always knew, no, 'friction modifiers' in a wet clutch.
But who would have known, (Except from the excellent advice on this site), that, Zinc, (ZDDP), was, still, needed in a, 'NEW', MC like this one.
Have used, 'STP', 'Marvel Mystery Oil', and now the, 'Lucas', in small, 'old' ICE engines. And they all have worked fine.. BUT, they are NOT 'wet' clutches.
Again. Do what ever you wish to do.
This is just what I do, and what I, 'would' do,
if ever I got a New S40, with 0 miles on it.
Which could happen, 'Almost bought one'
a, NEW, 2013 one, 0 miles, left over, at 4,875.00.
BUT, he wanted, (in addition to the Sales Tax),
$190.00 Prep, $320.00 Setup, 230.00, testing.
I'll keep looking.
