Best Engine Oil Type & Grade H22a??

[lewd lude lover]

Mine burns absolutely no oil at all. I never have to top it up. :smug smiley:

That's 'cause yours has been well looked after and you use the correct viscosity oil!


.

No it is because pushkis engine has never been over 6k. H22's are SUPPOSED to burn a bit of oil if used correctly

Putting two grades of oil depending on winter or summer in the UK is crazy.

10w40. that is the correct oil. research quality rather than going on price.. thats it.

It's better to burn a bit of oil because its thin than to use too thick of a grade. Oil squirters underneath each piston help the engine last forever, but also help oil get where it shouldn't and burned off.

OK. AFTER MUCH DELIBERATION I HAVE COME TO A DECISION.

This has been a real tough one to figure out! Wherever you look, everybody has a different opinion on this. I've done a lot of reading up over the past few days, and have taken advice from several sources to come to what I believe will be the best end result for my application.

Here's what I'm going to try;

OIL: MOTUL 300v Chrono, Fully Synthetic 10w40.

OIL FILTER: HAMP Shortie.

I won't know if this is the best combination till I try it. Whatever happens though, I'm sure it will work out just fine. I'm not going to be too far off getting it right I don't think.

I am trying the 10w40 viscosity because it would seem to be a good all-round safe bet. I was very close to deciding on 5w30, because being slightly thinner I figured it would help the engine components move more freely. And maybe it would. But the slightly thicker 40 will offer a bit of extra protection, will keep cooler, and will be less likely to seep through piston rings, for example. A common trait in older engines, leading to excessive oil consumption and a decrease in oil pressure. By going for a quality fully synthetic option, I expect to achieve less engine drag, better fuel economy, and overall better performance. How often I will need to top-up/change it, only time will tell. I have read very mixed reviews on this. But I'll post my findings when that becomes relevant.

I am trying the HAMP Shortie because it is used by top Japanese tuning companies, and was designed specifically with the vtec engines in mind. It supposedly increases oil pressure by 3-4 psi as well. Now whether that will help or hinder performance, I don't know. Again, I've read mixed reviews. I struggle to believe it is a negative feature, as they make a point of mentioning it in their ads. Only time will tell on that one anyway. If I'm pleased with the overall result, I may put the same oil in again but try a standard HAMP filter instead to see if I can feel the difference. That's the only way to be sure.

I think ultimately, from what I've discovered, when it comes to choosing oil & filters if you are truly happy with the way your engine runs then just keep doing what you're doing. If it doesn't feel quite right, then try something new. Everybody has a slightly different opinion, so the only way to find out really is to try for yourself.

I hope from the research I've done, and the info peeps have provided on this thread, I am making the right choice. I'll let you know how it goes. Should have it done within 2 weeks anyway. I'll repost then with the verdict.

Thanks for your input guys; always appreciated!

If you've got more to add, or you think I've made an error in judgement please post! I would like to hear your opinions.

Completely agreed.

Crunchy, go with what you've decided - it sure as heck won't cause any major harm.
In a car that's 19 years old, your ownership (what you do within it) will have a very small effect on total engine wear anyway, so don't lose any sleep either way

I think the interesting thing to watch with your choice (increased oil pressure and fully synthetic) is a gradual increase in any oil leaks more than anything else.

Yeah, that will be interesting to see. I'm hoping by using 10w40 rather than 5w30, that won't be too much of a problem. But like you say, it's a 19 year old engine so how much more harm can it do in the big scheme of things?

In fairness, having only owned the car for 6 weeks, I don't know if it's burning oil anyway. So how fair a test will it really be?

Tbh, as long as I can get it running noticeably better than it does already I'll be happy. I'm expecting to have to top up the oil every now & then, and have shorter intervals between changes regardless of what I use anyway. Simply because it's an older engine. That comes with the territory.

So I'll be keeping a close eye on everything initially anyway, meaning I can afford to take a few calculated risks for the possibility of improved performance & reliability.

See how it goes I guess..
