agreed, they arnt needed at all
So after approximately 5 months of running 10W30 Semi-synthetic. Unfortunately I've noticed a decrease in fuel economy, a friend of mine suggested that its causing more friction in the engine.
Anyway, I think I'll just stick to 15W engine oils. I think my mechanic has either Castrol GTX or Magnatec professional in a 15W40. So hopefully that brings things back to normal.
But feel free to suggest any 15W oils, that all you fellow Honda owners have had good experiences with.
Why 15? You're talking about cold viscosity.
It's the 30 that counts.
If there's more friction it's likely only because you're using a semi-synthetic rather than a full-synthetic.
Just go Penrite 5W-40 or 10W-50 IMO. I use 10W-50 and get low 7's/100KM. Sub-7's in the rural areas.
The other thing to take into consideration when choosing oil is heat dispertion. When you run a thin oil it does not have the same resistance to heat as a thicker oil, causong shear and breaking down quicker, resulting in oil burning off at a higher rate.
Well I've been checking my oil at least once a week on average. Oil consumption is absolutely fine. Last week, the dipstick was about 80 - 90% approximately.
The previous owners mechanic was running 15W40 (Castrol GTX). Then when my mechanic serviced it, he either put 10W40 or 15W40. Not entirely sure. But I didn't see much of a difference, so I think he may have used 15W40. Coz 15W40 was written on service reminded sticker on the windscreen, for the previous mechanic. So my mechanic may have also decided to use 15W40.
Also, people were saying that there wouldn't be much of a difference between 10W30, and 10W40. Hence why I think 15W40 might be best, and that there was a reason that the previous mechanic was putting that.
So you reckon full synthetic would be beneficial on DC2/DC4? I doubt they even came out of the factory with full synthetic, back in 1998.
Anyway I'll take HPR 10 into consideration. A lot of forum members seem to be recommending it a lot. Not just on this thread.
