HPS = High Performance Street. Kumbaga, timplado for modified engines.
Yung API certification kase, for consistency ang sine-certify compared sa standards.
Correct me if I'm wrong, sirs.
Hps is good but since olx seller is not a certified reseller of RP products we cant really say for sure.
If you want to be assured of what you buy, Purchase the oil from authorized resellers.
sir speedyfix,
meron kayong reseller sa Samar/Leyte province?
salamat.
You can check the label of the oil to see whether it can be used for gas and or diesel engines. Nakalagay naman duon.
Better use 15w/30 or 40 grade oil first and work your way up just to be safe.old engines have slight loose compression. Mas malapot kailagan yun oil. I don't recommend jumping to fully synthetic oil asap.
We have thicker viscosities if u need them. 20W50 is pretty popular with older toyotas.
Sirs, 5k kms interval pa rin po ba oil change interval kapag Royal Purple Oil ang gamit? Or longer po? Salamat po.
