Haflinger Engine Oil

Post by wojo1203 » Thu Dec 13, 2018 2:58 am

I have just purchased a 1974 700APT. What engine oil should I use? I'm in warm and sunny Queensland, Australia.

Good old fashioned mineral engine oil - 10w40 or the more usual 15W40. On old engines go up to #W50.

I did try Full Synthetic 5W30 once and the engine did not like it one bit - was almost as if I put water in it, so stay away from Full Synthetic.

Just one point, and there's a lot on the forum w.r.t engine Oil but it's scattered all over
under a multitude of different topics.

Be it a Hafe, Pinz, or C30X we run with SOLID lifters. You have to use oil with the proper
type and levels of anti-wear or you gonna end up with lifters that look like the one on the right.

Use motor Oil classified for "Classic cars" with solid lifters, or simply Diesel Engine oil with
designation CH-4, CL-4 or CJ-4 (most current). You do not want to use any API designation
of: SJ, SL, SM, or SN (most current) -- look on the back of the Oil for the API "Donut". The
formulation changed when Cat converters were eaten up by ZDDP which is the stuff you want
in your Oil. API decoding ring here:

30wt motor oil is O.E. read your service manual, most had a sticker stating 30wt

The term Wt is a bit before my time but googling 30wt it it comes up as 10W30 and the oil chart has a temp range of 10c to 30c.

This might be Ok for northern climates but here in an Aust summer it will need a 40wt (or higher) to deal with summer temps. We are regularly above 40 in mid summer.

Typically, the "30 Wt." refers to SAE 30, a mono-grade Oil -- oil with NO polymer addtives.
Today's formulation of mono-grades typically are for heavy duty or special use e.g., large 2-cycle,
diesel, tractors, and usually have proper levels of anti-wear.

Polymers were added to achieve multi-grade Oil. The "wt." loosely refers to the "weight"
e.g. 30 or 40 of the oil, technically this is not a weight but the viscosity index and not to be
confused with the "W" more commonly used which refers to a Winter blend. Most oils on the
shelf's today are multi-grade with a designation of xxWyy e.g. 10W30, the 10W part is the viscosity
index at cold and the 30 is the viscosity index at hot -- I know I am stating common knowledge.
The index in all cases be it a 10, 20 etc. refers to an actual viscosity set by SAE standards.

There are good choices for mono-grade oil and with good anti-wear, the Oil companies will designate
these as: 5W, 10W, 20W, SAE 30, SAE 40, etc. where the W is low viscosity for Winter use, the non-W
is summer.
