what oil you are using?

[JayJay]

Fuchs Titan, 5w40 fully-synth. Massive improvement over semi-synth espeically when cold.

i done this before and oil was leaking, back on semi and it was ok no leak.

i been said before by Honda engineers that fully s. oil shouldnt be used in this engine

I'd partly agree that a thicker oil may not result in an oil leak, but agree that a better oil and sorting out any leaks (or not) with new seals, etc should be the better option. Saying that I use semi 10W-40 and I got the same leaks you've mentioned...so not really sure there is any point here???

Do you have a link to that Honda engineers saying not to use fully synethetic? I can't find any mention of anyone saying not to use it, in fact everywhere I read it's being recommended

I do think it's a bit thin, but leaks are leaks. The engine run very smoothly with it. I could always switch to a 10w40 fully synth

i have that link somewhere, but its defo on PUK somewhere as this been discussed so many times

i personally stay with oil what was used when engine been designed

Honda don't say anything about synthetic/semi-synth, only he viscosity, and yes my viscosity is a bit low. I was thinking of going up to 10w40 next change.

[JayJay]

According to Honda, the H22 in the Mk5 Prelude:

"An oil viscosity of 5w30 is preferred for improved fuel economy and year-round protection in the vehicle."

The 10w30 is recommended if the ambient temperature exceeds 35 degrees celcius.

Turns out the ARB bushings are very worn as well, the whole bar is moving and knocking But as the shipping for them is twice the cost, I may just get a new ARB and bushings together as I wanted to replace it anyway.

Going to get another garage to check the suspension as well, check for any rubber bushings and worn parts the other place missed.

i get my 5w40 fully synthetic from morrisons £17 5lt bargain. i used to use 10w40 multi grade but a change of job forces i purchase oil
