Texaco Havoline 2-Cycle Oil

[gyropilot]

I have 5 gallons of Texaco Havoline 2-Cycle oil in gallon jugs for sale at $5.00 per gallon (only $1.25 per quart). Buyer picks up, or pays shipping from Tacoma, WA.

If you live in an area where this particular brand oil is hard to find, this might be a good opportunity to stock up. At a 50:1 mix ratio, 5 gallons of oil will cover 250 gallons of fuel.

This is a multi-purpose 2-cycle oil appropriate for either air or water cooled 2-cycle engines. However, it's not the most optimum oil for hotter running air-cooled 2-cycle engines like the Rotax 447 and 503... there are better oils out there specifically formulated for that type of engine.

From the Texaco Havoline product spec sheet:

Havoline Two-Cycle Engine Oil TC-W3 is recommended as a premium lubricant for use in two-stroke engines where the latest TC-W3 or earlier general purpose lubricants are recommended.

It is well suited for engines using oil injection systems with fuel/oil mixture ratios of up to 150:1. It meets the latest requirements of the NMMA TC-W3 performance standard, is formulated to meet ISO-L-EGB (JASO FB) passing criteria and meets API TC requirements for use in aircooled two-stroke applications.

On the back of the bottle, it claims to meet: TC-W, TC-WII, TC-W3, and ISO-L-EGB (JASO FB).



Best regards,

Changing to a new oil type John???

Yep... I've decided to try the Pennzoil Air-Cooled 2-cycle oil in my 503 until the need to do a teardown again (hopefully not for another 100 hours).

The switch is for two reasons:

1. After using the Havoline for only 25 hours and tearing down my engine (due to the cold-seizure I had back in June), I'm not impressed by the degree of carbon buildup in the exhaust ports and the partial lower ring sticking I found. I would have expected better after only 25 hours. On the other hand, the cylinder head domes and tops of the pistons were pretty clean. Overall, the carbon buildup wasn't too much worse than what I'd seen with the AV-2 I'd previously been using, but definitely not any better.

2. I've heard and read nothing but good reports and test results on the Pennzoil air cooled 2-cycle oil, so I thought I'd give that a try and see if it's better. Supposedly that oil is specifically designed to work best in hotter running air cooled 2-cycle engines, whereas oils like AV-2, the Havoline, and other multi-purpose 2-cycle oils are compromises. They work acceptably well in the 447 and 503 mind you, but they aren't the most optimum at resisting deposits.

There's nothing wrong with Havoline, I'm just not sure it's the best for an air cooled Rotax engine like a 447 or 503 and I'm at a good starting point to try something different. The Havoline is probably better used in the water cooled Rotax engines like the 582.

But then I could be wrong and wasting my money! In any case, I'm switching to the Pennzoil for the time being.

John,

I've been using Pennzoil for the last 3 years in our 503. When the rebuilder got it torn down, he was impressed with the minimum deposits in our engine. The only area which had any buildup was the underside of the piston domes, and I suspect that came from when the engine was run upside down. The friend I bought it from used it on his high thrustline Air Command before he bought a 582.

The compliments came from a guy who is a confirmed Amsoil user. He had to eat a little crow, as he was sure the engine would be full of carbon when he found out I used Pennzoil. His tune changed after the engine was apart.

One other reason we may have been pretty carbon free: I like to run my cruise temps at 1125 - 1150 degrees. I try not to let the cruise temps get below 11 if I can.

I think you'll like the Pennzoil, especially if running your temps a little higher.
