Oil weight in regards to burning - Honda Prelude Forum

ThatPreludeGuy · 09-03-2005, 09:46 AM

If I'm seeing high iron and burning oil with my 126k H22 would there be any advantage to moving to a 10w30 oil instead of the 5w30 I run now? Also I'm using Mobil 1, can I gain any longevity out of switching to something different?

Give castrol syntec 0w-30 a try. That's what im using in my euro-r motor. its thicker than most 5w, 10w-30 motor oils.

AllMotorBB6 · 09-03-2005, 03:13 PM

thats a crazy thin oil man.

PreludeDude01 · 09-03-2005, 04:40 PM

its like water....any improvements performance wise?

axio · 09-03-2005, 05:33 PM

uh yeah, isn't 0W30 thinner than 5W30, not thicker?

don't you mean THINNER?...

axio · 09-03-2005, 06:06 PM

Yeah, that's why I thought HRVstyle's post about 0W30 being thicker than 5W30 and 10W30 to be misinforming

I would start using 10w-30 now.. w/ those high miles....

The Castrol hes refering to is German Castroil and it supposibly heavier then other oils.

HRVstyle · 09-03-2005, 06:39 PM

Im not spreading misinfomation. Castrol Syntec 0w-30 is an ACEA A3 motor oil for high performance/extended drain intervals. This motor oil is thicker than mobil1 10w-30 at 40C, 100C, 150C. It is gets a 0w because it meets the specs at very cold temperatures. This oil is Porsche approved and meets the manufactures requirements for bmw longlife-01, MB 229.1,229.3,229.5, VW 505 00, 502 00, 503 00. Does your motor oil meet any of these manufacturer's approvals?

AllMotorBB6 · 09-03-2005, 06:41 PM

on the usdm motor with 125k, i used valvoline max life. Its a synthetic blend. It considerably dropped my oil usage. I used 10w30. I was amazed that my oil level at halfway between changes had only dropped one line on the stick, where prior to this oil (mobil 1 full synthetic) i had to add another quart.

Mkazm83 · 09-03-2005, 08:00 PM

Im gonna swich from Mobil 1 to Royal Purple, and see if it has any effect. Im still undecided about which weight im gonna go with.

Ic. I stand corrected

I actually just switched to the german castrol 0w-30 (5000 miles ago). Getting ready to send it in for the first analysis. Switched from Mobil1 5w-30.

Intresting, please post the results when they come back.

BTW is this being done at Blackstone Labs?

f0rk · 09-04-2005, 09:06 PM

yeah, through Blackstone. I'll bump this thread after I get the results, though it may be a week or two.

I noticed a reduction in oil consumption after switching back to Castrol SyntecBlend from Mobil 1. I've been running a combo of 10w30 and 10w40 for the second half of the summer. I'd say the oil consumption has been cut in half. I'm going to switch to a blend of 5w30 and 10w30 in 1000 miles, when my next change is due, for the winter. I'm @ 117k miles.

Mkazm83 · 09-04-2005, 11:00 PM

so what is the recomendation? 5-30 or 10-40 RP 79k

specbb6 · 09-04-2005, 11:09 PM

i'd go with 5-30
