hi guys, i drive a honda with a b18 twin cam engine. my question is can i use a 5w-20 oil in a tropical country (philippines)? will the 20 weight hot viscosity lubricate my engine adequately at high rpm's? or is this oil only specc'd for hybrids and lower performance cars in colder climates?
 
Didn't Honda switch to 5W20 with some of the K-series engines? And the B-series spec'ed a 30wt?
 
I've rented Fords (Ka and Escort) and Hondas (Civics) when in Brazil. 5w30 was recommended there.
Looking at Petrobras oil recommendation (no link here, but google petrobras and lubrax, then clik link 'O Melhor Lubrificante para o seu Veículo'):
2007 Ford Focus 2.0, 5w30 and 5W-40,
2005 Honda CR-V, 5W-40 and 15w40,
2007 Honda New Civic SI 2.0, 5w30, 10W-40 and 5W-40
 
Is it known what oil viscosities are easily available in other countries? I know you pretty much cant find 5w20 outside of the US.
 
I have no idea what the "best" oil viscosity for a Honda or Ford engine is. Just showing some examples from a country that has tropical climate..

If ONE type of oil was needed, it would be available.
 
5w-20 is available here in the philippines, it's penzzoil i think, i can get some at the local tru value store. just not sure about the thin visosity providing enough protection
 
The EPA requires that autos sold in the US specifically require that the weight oil used in the fuel economy tests be specified in the owner's manual. This does not mean that the engine must have this specific oil to survive.

Before this law came into effect, owner's manuals specified several different viscosities acceptable, depending on the ambient temperature. For example, I owned a Pontiac Bonneville from 1980 until 1986. Its manual specified oil as follows:

30 weight from 40 degrees to over 100
20W20, 20W40, and 20W50 -from 20 degrees to over
100.
10W30 and 10W40 from 0 degrees to over 100.
10 weight from 0 to 60.
5W30 from below -20 to +60
5W20 from below -20 to + 20.

Temperatures are in Fahrenheit. It appears that GM did not think much of the 5W20's and 5W30's back in the early 80's.
 
Well that's true, and I know of a few people that have used 5W20 in their Integra (or unless the OP has their B18 in another car) without any adverse effects. I ran Havoline 5W30 in my last OCI which is so thin you could almost call it a 5W20. I'm sending out the kit for analysis today so we'll see if the B18 prefers thicker or thinner. But as it stands, the manual states 5W30 for both the B18C1, B18B1, and all other variations in all countries.
 
Yes it will work in tropical climates. Keep it simple, do what the owners manual says. If it makes you feel better to go thicker to a 5w30, go ahead. You are giving up a fraction of a % of fuel economy - which is a big deal to OEMS, not necessarily to consumers. I don't think OEMs would recommend it if it would cause their engines to have poor engine life resulting in an unhappy customer (and a likely non-repeat buyer).

What does the owners manual recommend?




It says 5w30 for all temps and 10W30 for above freezing temps. But I just got done running Havoline DS 5W30 in my B18B1 and it's in the range of a heavier 20W and still showed great wear so my uneducated opinion is that a 5W20 would probably be okay, but I would still go with what Honda says.
